`ci/` for JavaScript regex

[verhovsky]

In JavaScript, regexes are written like

/[a-zA-Z0-9]/.test('some text')

I would like to quickly delete/change the contents of the Regex. Since the / are basically acting like quotes/brackets, I would like it if I could place my cursor between them and run ci/, ca/, di/ and da/ commands.

Describe alternatives you've considered
ct/ means I have to move the cursor more precisely.
