Simple javascript split() working as intended? [duplicate]

Question

fiddle: https://jsfiddle.net/jzhang172/4ntjykr0/

var x="pokemon,rykrkr";
x.split(",");
document.getElementById('ok').innerHTML=x[0];

<div id="ok"></div>

Isn't this supposed to show the whole word "pokemon" because I specified that it would split on comma?

Answer 1

.split doesn't alter the original string, so you have to do it like this:

var x = "pokemon,rykrkr";
var splited = x.split(",");

document.getElementById('ok').innerHTML = splited[0];

<div id="ok"></div>
