Javascript Array Functions

Without using a Javascript library such as JQuery, there are very few functions built into Javascript to deal with arrays. Here are a few of my own that often come in handy when working on projects.

In Array

This function checks to see if a value is in an array. JQuery has a built in function of the same name that does the same thing.

function inArray(value, array){
	for(var x=0;x<array.length;x++){
		if(array[x]==value){
			return 1;
		}
	}

	return 0;
}

Remove From Array

This function removes a value from an array.

function removeFromArray(value, array){
	for(var x=0;x<array.length;x++){
		if(array[x]==value){
			array.splice(x, 1);
		}
	}

	return array;
}

Simple bits of code, but of a lot of use when creating dynamic client side interfaces with Javascript. Let me know in the comments if you have any other little functions that you often use.
