javascript - remove array element on condition

Question

I was wondering how I\'d go about implementing a method in javascript that removes all elements of an array that clear a certain condition. (Preferably without using jQuery)

Answer 1

I love these kinds of questions and just a different version from me too... :)

Array.prototype.removeIf = function(expression) {
   var res = [];
    for(var idx=0; idx 3;
}
