Package Exports
- extra-array
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (extra-array) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
An array is a collection of values, stored contiguously.
Methods that modify any argument end in $. All other methods are functional,
and do not modify any parameters.
Stability: Experimental.
Unavilable array methods will be added here as its necessity is noticed.
const array = require('extra-array');
array.last([1, 2, 3]);
// 3
var a = [1, 2, 3, 4];
array.swap(a, 0, 1);
// [2, 1, 3, 4]
array.linspace(0, -1, 5);
// [0, -0.25, -0.5, -0.75, -1]
var a = [1, 2, 3, 4];
array.rotate(a, 1);
// [4, 1, 2, 3]
array.bsearchl([1, 3, 5, 7], 5);
// 2 ^ found
[...array.permutations([1, 2, 3])];
// [

// [ 1, 3, 2 ],
// [ 3, 1, 2 ],
