Editing js source file with extension

[Draco D. R.]

How would one change a js source file from a page and reload it back into the page through a chrome extension? I know you can edit source files with DevTools, but how do you do it with an extension? Thank you

The closest thing to that is probably content scripts and/or tabs.executeScript - both let you operate on the page's DOM from an "isolated world" javascript context, but if you need to modify the page's regular javascript context you can inject <script> tags into the DOM. 

If you only want to automate something in developer tools, extensions can provide additional functionality when devtools are open; see here for those APIs:
