How can I get query string values in JavaScript?

I'm kind of new to javascript and I was wondering if there was a better alternative to slice. I'm currently using window.location.slice at the moment and it feels like I could be using a better alternative. If you've ever used express.js you might have heard of "req.query.id", something like that in raw javascript would be perfect. Thanks, Alek.

Safely turning a JSON string into an object

For example: '[test,abc,123]'. How do you turn that into a standard javascript array that can be iterated?
This will work, but really you should fix your input to give you real JSON as is noted in the comments.
console.log(JSON.parse('["test","abc",123]'));

If so, how can I detect the difference between them.
I've noticed that you can't do typeof Array hence I'm looking for different solution to see the difference.
You can detect if a variable is an array by using Array.isArray(yourArray).

If you put this in the browser address bar (firefox/IE8):
javascript:alert(40.34+56.87)
Why the result comes as 97.2100000000001
when its supposed to be 97.21
javascript:alert((40.34+56.87).toFixed(2))
