Package Exports
- array-iterate
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 (array-iterate) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme

Array#forEach() with the possibility to change the next
position.
Installation
npm:
npm install array-iterateUsage
var iterate = require('array-iterate');
var isFirst = true;
var context = 'iterate';
iterate([1, 2, 3, 4], function (value, index, values) {
console.log(this, value, index, values)
if (isFirst && index + 1 === values.length) {
isFirst = false;
return 0;
}
}, context);

*/API
iterate(values, callback[, context])
Functions just like Array#forEach(), but when callback
returns a number, iterates over the item at number next.
Parameters
values(Array-like thing) — Values to iterate overcallback(Function) — Callback given toiterate.context(*, optional) — Context object to use when invokingcallback.
function callback(value, index, values)
Callback given to iterate.
Parameters
value(*) — Current iteration;index(number) — Position ofvalueinvalues;values(Array-like thing) — Currently iterated over.
Context
context, when given to iterate.
