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.

I have a link (string) which contains a filename. I need to extract the format of the filename but I am unfortunately not able to do that. An example link is given below
www.xyz.com/private/videos/89FDJKDKFgrFTD-MUyKE9Sn/source?file-name=SampleAudio_0.4mb.mp3&token=exp=1591202847~acl=/private/videos/8OJFREFJOIJFREJ-MUyKE9Sn/source*~hmac=aef161514cdfodsjfodsjorjef081b4c849b8c29c6a37339803866badfd4a16
I have tried multiple ways like to look for .(dot) until & but since I am new to this I couldn't make this work. I got the filename through name=([^&]*) but could not get the extension. Is there a way to do this?
You can use this regex:
(?:file-name=.*)(\..+)(?:&)

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]'));

I have web service which returns xml as plain string. I need to format it like xml beautifier does. I expect it to be performed on client side by JavaScript. How can I do that? What libraries is better fitted for this task?
One way of doing it is to use "JavaScript code prettifier" from Google.
You can find it here: http://google-code-prettify.googlecode.com/svn/trunk/README.html.
Follow the setup guide in the link and include the javascript file and then use it like so:
prettyPrintOne(XML_TO_BEAUTIFIED, 'xml')

I am trying to figure out how to get the parts of a URL I am going to be receiving from a third-party website. The URL I am expecting is something like: index.html?lob=company&ZipCode=22407
All of my pages are coded in .html rather than PHP due to my client's needs/desires, so my question is how can I get the "ZipCode" value.
In PHP this would be super simple, however I cannot do that.
Use Javascript instead.
var value_of_zipcode = "index.html?lob=company&ZipCode=22407".match("ZipCode=([0-9]{5})")[1];
now the value_of_zipcode is 22407
