zykadelic / array.includes.js

Last active December 19, 2015 21:29

See if the array contains the value, returns a boolean. Supports a detection between similar objects, but then requires the equalObjects function (https://gist.github.com/zykadelic/6020024).

	if(!Array.prototype.includes){
	Array.prototype.includes = function(value, detectSimilarObjects){
	if(typeof detectSimilarObjects === 'undefined' \|\| typeof value !== 'object'){
	detectSimilarObjects = false;
	}
	if(detectSimilarObjects === true && typeof equalObjects !== 'function'){
	throw Error("Array.includes() does not recognize equalObjects(). Get it here: https://gist.github.com/zykadelic/6020024");
	}
	for(i = 0; i < this.length; i++){
	if(detectSimilarObjects ? equalObjects(this[i], value) : this[i] === value){

	if(!object \|\| !otherObject \|\| isUnequalObject \|\| object[key] !== otherObject[key]){
