Operators provides the JavaScript operators as functions. It provides a standard, short,
and easy to remember interface for addition, multiplication, concatenation, and-ing, or-ing, as well as several two parameter lambdas for non-associative operators, and curried
versions of the binary operators for quick creation of the functions that you end up writing for map and filter all the time.
Use it with qualified imports with the yet unfinished module import syntax or attach it to the short variable of choice. For selling points, here's how it will look with ES7 modules.
import { gt, plus, pow, eq, prepend } from 'operators'
[1,3,2,6,5,4].filter(gt(4));
// [ 6, 5 ]
[1,2,3,4].map(plus(1)); // [ 2, 3, 4, 5 ]
[1,2,3,4].map(pow(2)); // [ 1, 4, 9, 16 ]
[1,2,3,2].filter(eq(2)); // [ 2, 2 ]
[ [1,2], [3,4] ].map(prepend([0])); // [ [ 0, 1, 2 ], [ 0, 3, 4 ] ]Read the API.
