new-array

stable

Creates a new dense array with the given size, optionally filled with a specified value.

var array = require('new-array')
 
array(2)
// > [ undefined, undefined ]
 
array(4, 0)
// > [ 0, 0, 0, 0 ]
 
array()
// > []
 
array(2).map((x, i) => i)
// > [0, 1]

Primarily motivated by the fact that new Array(n) produces an array of holes that does not play well with methods like Array#map().

Usage

NPM

arr = newArray(n[, value])

Returns a new dense array with length n (default 0), where each element is set to value (or undefined).
