Dodos

Pandas-inspired transducer-based data wrangling library for js

On npm: https://www.npmjs.com/package/dodos

NOTE: This is very much a work in progress for now

 
array = [
  [1, 2, 3],
  [3, 4, 5],
]
 
index = ['columnA', 'columnB', 'columnC']
 
const dodo = new Dodo(array, index)
 
dodo.col('columnA').toArray() // [1, 3]
 
dodo.filterBy('columnB', b => b == 4).toArray() // [4]
 
dodo.col('columnA').sum() // 4
 

All methods return a new instance, leaving the original untouched. All operations on the array are evaluated only when calling .toArray() or when calling a .reduce() method (eg. .sum()).

For now, please refer to the tests for more usage examples.
