or

Returns the element of an array when the callback returns true.

Purpose

This module provides a similar function as Array.prototype.filter, but it returns the element, not an array. And it stops looping as soon as it finds a result.

Usage

var arr = ['item', 'other', 'finally'];
 
var item = or(arr, function(item) {
    return item === 'other';
});
 
console.log(item); // "other"
 
// Real world example
var matchesSelector = or(['matchesSelector', 'mozMatchesSelector',
    'webkitMatchesSelector', 'oMatchesSelector',
    'msMatchesSelector'], function(shim) {
    return shim in document.documentElement;
});
 
document.getElementById('some')[matchesSelector]('#some'); // true

API

The module returns a function accepting the following arguments:

• array: the array on which to iterate
• callback: the function being called
• context: the context on which to call the callback
