+- ...net Explorer brauerning turli xil versiyalari uchun "Trident" va "Chakra", Microsoft Edge uchun "ChakraCore", Safari uchun "Nitro" va "SquirrelFish" va boshqalar kabi boshqa kod nomlari mavjud.
 
-The terms above are good to remember because they are used in developer articles on the internet. We'll use them too. For instance, if "a feature X is supported by V8", then it probably works in Chrome and Opera.
+Yuqoridagi atamalarni eslab qolish yaxshi, chunki ular netdagi ishlab chiquvchilar maqolalarida qo'llaniladi. Biz ulardan ham foydalanamiz. Masalan, agar "X funktsiyasini V8 qo'llab-quvvatlasa", ehtimol u Chrome va Opera-da ishlaydi.

+## Brauzerdagi JavaScript nimani bajara oladi?
 
-Modern JavaScript is a "safe" programming language. It does not provide low-level access to memory or CPU, because it was initially created for browsers which do not require it.
+Zamonaviy JavaScript - bu "xavfsiz" dasturlash tili. Bu xotira yoki protsessorga(CPU) past darajadagi kirishni ta'minlamaydi, chunki dastlab uni talab qilmaydigan brauzerlar uchun yaratilgan.
 
-JavaScript's capabilities greatly depend on the environment it's running in. For instance, [Node.js](https://wikipedia.org/wiki/Node.js) supports functions that allow JavaScript to read/write arbitrary files, perform network requests, etc.
+JavaScript-ning imkoniyatlari u ishlayotgan muhitga juda bog'liq. Masalan, [Node.js](https://wikipedia.org/wiki/Node.js) JavaScript-ga o'zboshimchalik bilan fayllarni o'qish / yozish, tarmoq so'rovlarini bajarish va hk.
 
-In-browser JavaScript can do everything related to webpage manipulation, interaction with the user, and the webserver.
+Brauzerda JavaScript veb-sahifani boshqarish, foydalanuvchi bilan o'zaro aloqasi va veb-server bilan bog'liq barcha narsani amalga oshirishi mumkin.
 
 Masalan: 
 
-- Add new HTML to the page, change the existing content, modify styles.
-- React to user actions, run on mouse clicks, pointer movements, key presses.
-- Send requests over the network to remote servers, download and upload files (so-called [AJAX](https://en.wikipedia.org/wiki/Ajax_(programming)) and [COMET](https://en.wikipedia.org/wiki/Comet_(programming)) technologies).
-- Get and set cookies, ask questions to the visitor, show messages.
-- Remember the data on the client-side ("local storage").
+- Sahifaga yangi HTML qo'shish, mavjud tarkibni o'zgartirish, uslublarni o'zgartirish.
+- Foydalanuvchining harakatlariga munosabat bildirish, sichqonchani bosish, ko'rsatgich harakatlari, tugmachalarni bosish bilan ishlash.
+- Uzoq serverlarga tarmoq orqali so'rov yuboring, fayllarni yuklab olish va yuklash(deb nomlangan [AJAX](https://en.wikipedia.org/wiki/Ajax_(programming)) va [COMET](https://en.wikipedia.org/wiki/Comet_(programming)) texnologiyalar).
+- Cookies-ni olish va o'rnatish, tashrif buyuruvchiga savollar berish, xabarlarni ko'rsatish.
+- Mijoz tomonidagi ma'lumotlarni eslab qolish("mahalliy saqlash").
 
-## What CAN'T in-browser JavaScript do?
+## JavaScript-da brauzerda nima qila olmaysiz?
 
-JavaScript's abilities in the browser are limited for the sake of the user's safety. The aim is to prevent an evil webpage from accessing private information or harming the user's data.
+JavaScript-ning brauzerdagi imkoniyatlari foydalanuvchi xavfsizligi uchun cheklangan. Maqsad yomon veb-sahifaning shaxsiy ma'lumotlarga kirishini yoki foydalanuvchi ma'lumotlariga zarar etkazishini oldini olishdir.
 
-Examples of such restrictions include:
+Bunday cheklovlarga quyidagilar kiradi:
 
-- JavaScript on a webpage may not read/write arbitrary files on the hard disk, copy them or execute programs. It has no direct access to OS system functions.
+- Veb-sahifadagi JavaScript-ni qattiq diskdagi o'zboshimchalik bilan fayllarni o'qish / yozish, ularni nusxalash yoki dasturlarni bajarish mumkin emas. Uning OS tizimi funktsiyalariga to'g'ridan-to'g'ri kirish imkoniyati yo'q.
 
-    Modern browsers allow it to work with files, but the access is limited and only provided if the user does certain actions, like "dropping" a file into a browser window or selecting it via an `<input>` tag.
+    Zamonaviy brauzerlar unga fayllar bilan ishlashga imkon beradi, lekin kirish cheklangan va faqat foydalanuvchi brauzer oynasiga faylni "tushirish" yoki uni `<input>` yorlig'i orqali tanlash kabi ba'zi bir amallarni bajargan taqdirdagina taqdim etiladi.
 
-    There are ways to interact with camera/microphone and other devices, but they require a user's explicit permission. So a JavaScript-enabled page may not sneakily enable a web-camera, observe the surroundings and send the information to the [NSA](https://en.wikipedia.org/wiki/National_Security_Agency).
-- Different tabs/windows generally do not know about each other. Sometimes they do, for example when one window uses JavaScript to open the other one. But even in this case, JavaScript from one page may not access the other if they come from different sites (from a different domain, protocol or port).
+    Kamera / mikrofon va boshqa qurilmalar bilan o'zaro aloqa qilish usullari mavjud, ammo ular foydalanuvchidan aniq ruxsat talab qiladi. Shunday qilib, JavaScript-ni qo'llab-quvvatlaydigan sahifa veb-kamerani yashirincha yoqmasligi, atrofni kuzatishi va ma'lumotni[NSA](https://en.wikipedia.org/wiki/National_Security_Agency) ga yuborishi mumkin emas.
+- Turli xil yorliqlar / oynalar odatda bir-birlarini bilishmaydi. Ba'zan ular bilishadi, masalan, bitta oyna ikkinchisini ochish uchun JavaScript-ni ishlatganda. Ammo bu holatda ham bitta sahifadagi JavaScript-ni boshqa saytlarga kirish mumkin emas, agar ular turli saytlardan (boshqa domendan, protokoldan yoki portdan) bo'lsa.
 
-    This is called the "Same Origin Policy". To work around that, *both pages* must contain a special JavaScript code that handles data exchange.
+    Bu "Xuddi shu manba siyosati"(Same origin policy) deyiladi. Buning uchun *ikkala sahifa* ma'lumotlar almashinuvi to'g'risida kelishib olishlari va uni boshqaradigan maxsus JavaScript kodini o'z ichiga olishi kerak. Biz buni o'quv qo'llanmasida ko'rib chiqamiz.
 
-    This limitation is, again, for the user's safety. A page from `http://anysite.com` which a user has opened must not be able to access another browser tab with the URL `http://gmail.com` and steal information from there.
-- JavaScript can easily communicate over the net to the server where the current page came from. But its ability to receive data from other sites/domains is crippled. Though possible, it requires explicit agreement (expressed in HTTP headers) from the remote side. Once again, that's a safety limitation.
+    Ushbu cheklov, yana foydalanuvchi xavfsizligi uchun. Foydalanuvchi ochgan sahifa `http://anysite.com` URL manzili bo'lgan boshqa brauzer yorlig'iga kira olmasligi kerak `http://gmail.com` va u erdan ma'lumotlarni o'g'irlash.
+    
+- JavaScript joriy sahifa kelgan serverga tarmoq orqali osongina aloqa qilish mumkin. Ammo uning boshqa saytlardan / domenlardan ma'lumotlarni qabul qilish qobiliyati nogiron. Iloji bo'lsa ham, bu uzoqdan aniq kelishuvni (HTTP sarlavhalarida ko'rsatilgan) talab qiladi. Yana bir bor bu xavfsizlikni cheklash.
 
 ![](limitations.svg)
 
-Such limits do not exist if JavaScript is used outside of the browser, for example on a server. Modern browsers also allow plugin/extensions which may ask for extended permissions.
+Agar JavaScript brauzerdan tashqarida, masalan serverda ishlatilsa, bunday cheklovlar mavjud emas. Zamonaviy brauzerlar kengaytirilgan ruxsat so'rashi mumkin bo'lgan plagin / kengaytmalarga ham imkon beradi.
 
 ## JavaScript-ni qaysi xususiyatlari uni noyob qiladi?
 
 JavaScript hech bo'lmaganda *uchta* ajoyib xususiyatga ega:
 
 ```solishtiring
-+ HTML/CSS bilan to'liq integratsiyasi.
++ HTML va CSS bilan to'liq integratsiyasi.
 + Oson ishlar osongina amalga oshiriladi.
-+ Barcha asosiy brauzerlar tomonidan qo'llab-quvvatlanadi va ularda sukut bo'yicha yoqilgan.
++ Barcha asosiy brauzerlar tomonidan qo'llab-quvvatlanadi va ularda standart sifatida yoqilgan.
 ```
 JavaScript - bu uchta narsani birlashtirgan yagona brauzer texnologiyasidir.
 
-Bu JavaScript-ni noyob qiladi. Shuning uchun u brauzer interfeyslarini yaratishda eng keng tarqalgan vositadir.

-# Code editors
+# Kod muharrirlari
 
-A code editor is the place where programmers spend most of their time.
+Kod muharriri bu dasturchilarning ko'p vaqtini sarflaydigan joy.
 
-There are two main types of code editors: IDEs and lightweight editors. Many people use one tool of each type.
+Kod muharrirlarining ikkita asosiy turi mavjud: IDE va engil muharrirlar. Ko'p odamlar har bir turdagi bitta vositadan foydalanadilar.
 
 ## IDE
 
-The term [IDE](https://en.wikipedia.org/wiki/Integrated_development_environment) (Integrated Development Environment) refers to a powerful editor with many features that usually operates on a "whole project." As the name suggests, it's not just an editor, but a full-scale "development environment."
+[IDE](https://en.wikipedia.org/wiki/Integrated_development_environment) atamasi (Integrated Development Environment, "Integratsiyalashgan rivojlanish muhiti") odatda "butun loyiha" da ishlaydigan ko'plab xususiyatlarga ega kuchli muharrirni nazarda tutadi. Nomidan ko'rinib turibdiki, bu nafaqat muharrir, balki keng ko'lamli "taraqqiyot muhiti".
 
-An IDE loads the project (which can be many files), allows navigation between files, provides autocompletion based on the whole project (not just the open file), and integrates with a version management system (like [git](https://git-scm.com/)), a testing environment, and other "project-level" stuff.
+IDE loyihani yuklaydi (bu juda ko'p fayl bo'lishi mumkin), fayllar o'rtasida navigatsiyani amalga oshirishga imkon beradi, butun loyiha (faqat ochiq faylga emas) asosida avtomatik to'ldirishni ta'minlaydi va versiyalarni boshqarish tizimiga (masalan, [git](https://git-scm.com/)), sinov muhiti va boshqa "loyiha-darajasidagi" narsalar.
 
-If you haven't selected an IDE yet, consider the following options:
+Agar siz IDE ni tanlamagan bo'lsangiz, quyidagi variantlarni ko'rib chiqing:
 
-- [WebStorm](http://www.jetbrains.com/webstorm/) for frontend development. The same company offers other editors for other languages (paid).
-- [Netbeans](http://netbeans.org/) (free).
+- [Visual Studio Code](https://code.visualstudio.com/) (o'zaro faoliyatli platforma, bepul).
+- [WebStorm](http://www.jetbrains.com/webstorm/) (o'zaro faoliyatli platforma, pullik).
 
-All of these IDEs are cross-platform.
+Windows uchun "Visual Studio" ham mavjud, "Visual Studio Code" bilan aralashmaslik kerak. "Visual Studio" - bu pullik va qudratli Windows muharriri .NET platformasi uchun juda mos keladi. Bundan tashqari, JavaScript-da yaxshi. Bepul versiyasi ham mavjud [Visual Studio Community](https://www.visualstudio.com/vs/community/).
 
-For Windows, there's also "Visual Studio", not to be confused with "Visual Studio Code." "Visual Studio" is a paid and mighty Windows-only editor, well-suited for the .NET platform. A free version of it is called [Visual Studio Community](https://www.visualstudio.com/vs/community/).
+Ko'pgina IDElar pullik, ammo bepul sinov muddati bor. Ularning narxi malakali dasturchilarning ish haqi bilan taqqoslaganda odatda ahamiyatsiz, shuning uchun ozingizga eng qulayini tanlang.
 
-Many IDEs are paid but have a trial period. Their cost is usually negligible compared to a qualified developer's salary, so just choose the best one for you.
+## Engil muharrirlar
 
-## Lightweight editors
+"Yengil muharrirlar" IDE'lar kabi kuchli emas, lekin ular tezkor, nafis va sodda.
 
-"Lightweight editors" are not as powerful as IDEs, but they're fast, elegant and simple.
+Ular asosan faylni bir zumda ochish va tahrirlash uchun ishlatiladi.
 
-They are mainly used to open and edit a file instantly.
+"Yengil muharrir" va "IDE" ning asosiy farqi shundaki, IDE loyiha darajasida ishlaydi, shuning uchun u boshlanganda juda ko'p ma'lumotlarni yuklaydi, kerak bo'lsa loyiha tuzilishini tahlil qiladi va hokazo. Agar bizga bitta fayl kerak bo'lsa, engil muharrir juda tez ishlaydi.
 
-The main difference between a "lightweight editor" and an "IDE" is that an IDE works on a project-level, so it loads much more data on start, analyzes the project structure if needed and so on. A lightweight editor is much faster if we need only one file.
+Amalda yengil muharrirlarda juda ko'p plaginlar bo'lishi mumkin, shu jumladan direktoriya-darajasidagi sintaksis analizatorlari va avtokompleterlar, shuning uchun engil muharrir va IDE o'rtasida qat'iy chegara yo'q.
 
-In practice, lightweight editors may have a lot of plugins including directory-level syntax analyzers and autocompleters, so there's no strict border between a lightweight editor and an IDE.
+Quyidagi variantlar sizning e'tiboringizga loyiqdir:
 
-The following options deserve your attention:
+- [Atom](https://atom.io/) (o'zaro faoliyatli platforma, bepul).
+- [Sublime Text](http://www.sublimetext.com) (o'zaro faoliyatli platforma, shartli ravishda bepul).
+- [Notepad++](https://notepad-plus-plus.org/) (Windows, bepul).
+- [Vim](http://www.vim.org/) va [Emacs](https://www.gnu.org/software/emacs/) ham zo'r agar ularni qanday foydalanishni bilsangiz.
 
-- [Visual Studio Code](https://code.visualstudio.com/) (cross-platform, free) also has many IDE-like features.
-- [Atom](https://atom.io/) (cross-platform, free).
-- [Sublime Text](http://www.sublimetext.com) (cross-platform, shareware).
-- [Notepad++](https://notepad-plus-plus.org/) (Windows, free).
-- [Vim](http://www.vim.org/) and [Emacs](https://www.gnu.org/software/emacs/) are also cool if you know how to use them.

-## My favorites
+Yuqoridagi ro'yxatlardagi muharrirlar men yoki men yaxshi dasturchi deb hisoblaydigan do'stlarim uzoq vaqt davomida foydalanishgan va baxtli bo'lganlar.
 
-The personal preference of the author is to have both an IDE for projects and a lightweight editor for quick and easy file editing.
+Bizning katta dunyoda boshqa buyuk muharrirlar ham bor. Iltimos, o'zingizga eng yoqqanini tanlang.
 
-I'm using:
-
-- As an IDE for JS -- [WebStorm](http://www.jetbrains.com/webstorm/) (I switch to one of the other JetBrains offerings when using other languages)
-- As a lightweight editor -- [Sublime Text](http://www.sublimetext.com) or [Atom](https://atom.io/).

-## Let's not argue
-
-The editors in the lists above are those that either I or my friends whom I consider good developers have been using for a long time and are happy with.
-
-There are other great editors in our big world. Please choose the one you like the most.
