How to convert string into boolean?

Question

I read out a data-attibute, then I want to convert the string "true" into a boolean. At the moment I have to do a comparison in the javascript, is there a better way to do it? I don't know how to use this solution

HTML

<div data-nav='{ "nav": "true"}'>

JS

    var data = JSON.parse($nav.attr('data-nav').toString());
    data.nav = (data.nav === "true") ? true : false;

Personally I would do it the way you did: `data.nav = (data.nav === "true") ? true : false; ` — jhhoff02, Jun 29 '16 at 14:16
...except that the `? true : false` part is totally redundant. — JJJ, Jun 29 '16 at 14:17

Try

<div id='test' data-nav='true'>


var truefalse = $('#test').data('nav');

.data should be able to evaluate it as boolean

here is an example in JSFiddle https://jsfiddle.net/lismore/hx3gLvgw/
