In the documentation, it says:

digitalPulse is for SHORT pulses that need to be very accurate. If
you're doing anything over a few milliseconds, use setTimeout instead.

How many milliseconds is too many milliseconds?

I'd say 1000ms is a good start.

It's not a hard limit at all and there are times you might want to use more, but:

• digitalPulse is asyncronous - other code will keep executing while it pulses the pin
• When it's running, Espruino can't enter 'deep sleep' modes, so will use more power
