Is it necessary to use `.call` for filter and reduce. Can I just normally call the predicate with the array element ? like

Array.prototype.myfilter = function (func) {

let arr = this;

let newArr = [];

for (let i = 0; i < arr.length; i++) {

if (func(arr[i])) {

newArr.push(arr[i]);

}

}

return newArr;

};
