What you're after is filter
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter
This will allow you to do the following:
var ary = ['three', 'seven', 'eleven'];
var aryWithoutSeven = ary.filter(function(value) { return value != 'seven' });
console.log(aryWithoutSeven); // returns ['three', 'eleven']
