Remove all elements from array that match specific string

by

Simply use the Array.prototype.filter() function for obtain elements of a condition

var array = [1,2,'deleted',4,5,'deleted',6,7];
var newarr = array.filter(function(a){return a !== 'deleted'})

Update: ES6 Syntax

let array = [1,2,'deleted',4,5,'deleted',6,7]
let newarr = array.filter(a => a !== 'deleted')
