How to make a JavaScript request through a proxy?

Question

JavaScript

Good day.
The task is to make ajax requests through a request (and the proxies are always different). That is, a new proxy is used for each new request. This must be done without php, node.js and other server languages. (Client js -> proxy server -> requested resource).
I spent a lot of time searching for a solution on the Internet, but everywhere it is suggested to use node.js or php.
Thanks in advance.
Client js is a plugin for Chrome.

Chrome has the same API for setting a proxy: https://developer.chrome.com/extensions/proxy
