Can someone help me understand toString()?

Question

I've been having problems printing arrays and I need some help. I googled it but didn't find a satisfying explanation (more accurately, I understood almost nothing). Can anybody tell me how to use it and give me an example about it, please?

Answer 1

It's pretty straight forward. It does what its name implies, transforms an object into a string.

Imagine we have this:

var arr = [ 0, 1, 2 ];

console.log(arr.toString());

// output: 0,1,2

give it a try, get familiar with it
