A feature called Snippets is present in the DevTools which allows you to save (or remove) bits of code which can be run on a webpage (it's just a bit more convenient than re-typing JavaScript code in the console panel). To try it:
- Go to Sources > Snippets (it's in the left sidebar)
- Right click in the snippets window and select New
- Enter a file name and your desired snippet
- Right click on the snippet and select Run (or
Ctrl/Cmd + Enter
)
You'll also notice it has multi-line editing and confirmation for exit-without-saving.
