What will be the result of the code?

console.log(new Array(5).join('5'));
new Array(5) creates new array without elements and with length = 5, example: var a = new Array(5); a.length // 5 join() method joins the elements of an array into a string, and returns the string and returns the string of elements separated by a specified separator. Example: a.join(5); // returns "5555" Empty 5 length array separated by '5' seperator;

It's really cool question!

WHY the correct answer is 5555 typeof Number, not String???
