@proem/array

@proem/array

Utility package for handling arrays.

Usage

First, import the @proem/array module is imported into the namespace

import array from '@proem/array';

@proem/array provides custom implementations for convenience functions already implemented by the Array.prototype, such as the map function. The semantics might differ, for example the array.map in proem trades the support of sparse arrays for performance.

const input = [1, 2, 3, 4, 5]

const output = array.map(input, n => n + 1)  // [2, 3, 4, 5, 6, 7]

Some functions have their partially applicable counterparts. For example, proem provides the array.map.partial, which returns a function applicable to arrays.

const a = ["a,", "b", "c"]
const b = ["d", "e", "f"]

const partial = map.partial((str: string) => str.toUpperCase())

const output = partial(a) // [ 'A,', 'B', 'C' ]

const otherOutput = partial(b) // ['D', 'E', 'F']
