Tell us what’s happening:
It returns an empty array. Why?
Your code so far
// the global Array
var s = [23, 65, 98, 5];
Array.prototype.myFilter = function(callback){
var newArray = [];
// Add your code below this line
this.forEach(item => {
newArray.push(callback(item) === true);
});
// Add your code above this line
return newArray;
};
var new_s = s.myFilter(function(item){
return item % 2 === 1;
});
