Safely turning a JSON string into an object

Given a string of JSON data, how can you safely turn that string into a JavaScript object?

Obviously you can do this unsafely with something like...

var obj = eval("(" + json + ')');

...but that leaves us vulnerable to the json string containing other code, which it seems very dangerous to simply eval.

JSON.parse(jsonString)是一种纯粹的JavaScript方法，只要你能保证一个合理的现代浏览器。

The jQuery method is now deprecated. Use this method instead:

let jsonObject = JSON.parse(jsonString);

Original answer using deprecated jQuery functionality:

If you're using jQuery just use:

jQuery.parseJSON( jsonString );

It's exactly what you're looking for (see the jQuery documentation).

Edit: This answer is outdated and Jonathan's answer above ( JSON.parse(jsonString) ) is now the best answer.

JSON.org has JSON parsers for many languages including 4 different ones for Javascript. I believe most people would consider json2.js their goto implementation.
