chainy-plugin-map v1.0.5

Chainy action that replaces each item in the array with the result of an asynchronous or synchronous iterator

The iterator can operate synchronously:

function (value) {
	return replacementValue
}

Or asynchronously:

function (value, complete) {
	complete(err, replacementValue)
}

Iterators are executed in parallel.

The replacement value (or lack thereof) is used to replace the value of the item in the array the iterator was executing for. Be sure to always explicitly specify a replacement value (even if it is the same as the value), as otherwise the item in the array will be replaced with undefined and you'll be confused.

Example:

require('chainy').create().require('set map log')
	.set([1, 2, 3])

	// Synchronous iterator
	.map(function (i) {
		return i * 5;
	}).log()  // [5, 10, 15]

	// Asynchronous iterator
	.map(function (i, next) {
		return next(null, i * 10);
	}).log()  // [10, 20, 30]
