 dataframe-js provides another way to work with data in javascript (browser or server side) by using DataFrame, a data structure already used in some languages (Python, R, ...).
 
 A DataFrame is simply built on two concepts:
-- **Columns** providing ways to select your data and reorganize them.
-- **Rows** providing ways to modify or filter your data.
