My personal habit is using isNaN to detect number in JavaScript since typeof NaN also returns number, feel free if it's over-defend :)

Good catch. Will change that, thanks! :)

Is there a reason not to use default value, then you could remove the number type check?!

It's Tracekit, so we have to be very defensive in here. It's guarding us in case React breaks something, or someone decides to put framesToPop property on their error objects.

Ahh and changelog plz! |

Number.isNaN is totally different than isNaN, since Number.isNaN detects if it's NaN or not, isNaN detects if it is Not A Number, you should also check value 0 as your previous logic: if (isNaN(popSize) || popSize === 0)
Number.isNaN('sentry'); // false
isNaN('sentry'); // trueBTW, Number.isNaN seems not work so good on IE browsers, haven't checked yet. Would be nice if I can get some information abt it from yours XD

@jiananshi I know how they work, thanks for pointing that out anyway :)
I can skip 0 logic, as slice(0) returns the same array, thus passing popSize === 0 will be effectively no-op.
Yes, Number.isNaN is not IE friendly, but we already use it in our codebase. It's mentioned here https://docs.sentry.io/platforms/javascript/#browser-table

Fine, let's take a step back and compare with the previous code:
// previous
if (typeof popSize !== 'number' || popSize === 0)
// current
if (Number.isNaN(popSize))In the previous logic you do want a NUMBER but currently anythings besides NaN is acceptable, not sure if that's what you want.
btw the browser-table is a nice design, just learned that.

Thankfully it will work just fine anyway, as slice can accept anything and it'll disregard anything other than a number. Thus this check is completely redundant anyway. Will remove it in the next patch release. Thanks and excuse my stubbornness 😅

It's ok, as english is not my mother language previous comment may feel little bit annoying, if it is, pls don't mind.
