Override Javascript file in chrome

Question

I would like to override a javascript file with my own version of the similar javascript file in chrome.

Let me explain:

1) Lets say a site \'http://example.

Answer 1

There are plugins and tools in Chrome for these purposes:

1. Chrome's DevTools, tab Local Overrides (supported from Chrome 65)
2. Requestly
3. Resource Override
4. You might also want to use Tamper, which is a mitmproxy based devtools extension that lets you edit remote files locally and serve them directly to Chrome. (but it's more headache to install and use it)

Choose the one which is easier to use for you.
