Answer 1

Use filter() for filtering elements from an array

 var A = ['a', 'del', 'b', 'del', 'c']; var B = A.filter(function(v) { return v != 'del'; }); console.log(B);

For older browser check polyfill option of filter method .

In case if you want to remove element from existing array then use splice() with a for loop

 var A = ['a', 'del', 'b', 'del', 'c']; for (var i = 0; i < A.length; i++) { if (A[i] == 'del') { A.splice(i, 1); // remove the eleemnt from array i--; // decrement i since one one eleemnt removed from the array } } console.log(A);
