$.map

Iterates over each item in an array or object, and runs a callback function. The results are returned as an array. Note that if an array is returned from the callback function, it will be flattened into the resulting array.

Usage

$.map(array);
$.map(object);

array

An array to apply the callback to each item of.

object

An Object to apply the callback to each item of.

Returns

An array containing the result of each callback. If the result of a callback is an array, it will be flattened into the return array. If the result of a callback is null or undefined, it will not be returned in the array.

Example

const items = [42, "hello", ["my", "your"]],
	arr = $.map(items, item => typeof item === "string" ? item + " world" : null);

console.log(arr); // ["hello world", "my world", "your world"]
