[Javascript] Iterate over Items with JavaScript ' s for-of Loop

In this lesson we'll understand the for of loop in Javascript which is introduced in ES6. The for-of loop lets you iterate of an Itterable object (array, string, set, or map) and returns each objects value in a s Pecified variable. This excludes plain objects as we'll see in the lesson.

Object.prototype.objCustom =function() {}; Array.prototype.arrCustom=function() {};let iterable= [3, 5, 7];iterable.foo= ' Hello '; for(Let Iinchiterable) {Console.log (i);//0, 1, 2, "foo", "Arrcustom", "Objcustom"} for(Let Iinchiterable) {  if(Iterable.hasownproperty (i)) {console.log (i);//0, 1, 2, "foo"  }} for(Let I of Iterable) {console.log (i);//3, 5, 7}

"Acccustom" and "Objcustom" are not logged in second loop was because they are inherited. Not array and object ' s own prop.
