When to use strict mode?

[ocon]

I know the benefits of using strict mode to test out the script, but should it only be used for testing?

It seems to benefit is finding errors. If there are some errors that slip by during testing, I would rather they silently fail and not take down the whole page.

Should I remove strict mode before putting the code live or do most people keep it in their code?

A lot of what strict mode enforces is syntax and would be picked up in testing. No idea what most people do, probably never use strict mode at all.

I would leave it in, 'silently fail' means you have no idea what is happening, depending on nature of site that could be a bigger danger to you business.
