JS: make sanitization a "common" technique rather than "important"

[esbena]

It was pointed out that sanitization is bordering on being an anti-pattern, and that we should make it clearer in our documentation that better alternatives exist.
I have therefore changed the "sanitization is important" formulations to "sanitization is common", and added an example of an alternative where appropriate.

I like it! 👍

You could put the An even safer alternative texts first in the <recommendation>.
(E.g. IncompleteSanitization.qhelp: the first proposal given in <recommendation> is to keep using sanitization).

That would require a bit more rewriting, but I think it could be good to present the safest option first.

but I think it could be good to present the safest option first.

I think the order is fine. We are generally recommending local fixes for the alerts we produce, not architectural rewrites.

Ping @mchammer01 for a minor doc review

I'll leave it up to the documentation team to decide whether it's preferable to say "isn't" or "is not".

Thanks for making the help more precise and helpful to users. I've made one suggestion several times, but otherwise the changes LGTM once the tests pass.

[esbena]

Thank you all. I have applied @felicitymay's suggestions, and just need a final approval.

@esbena - thanks for the ping and sorry for not responding (I was away yesterday.)
Thanks Felicity for looking at this.
