Devtools Break On Expression

I would like to suspend everything when a given Javascript expression is true. I have seen conditional breakpoints, but that doesn't work for me, because that would require setting

Solution 1:

Type the following in Devtools console:

setInterval(function() {
    if(<yourcondition>) {
        debugger;
    }
}, 10);

This will poll for that condition every 10 ms, and break when it is met.

You can adjust 10 to be looser if that works for you. A 10 ms frequency is already a big strain on processor.
