Wait it is slower to push an item into an array than do this? 🤯

I think the general answer is "yes, it's faster", but there are differences between JS engines which make the testing somewhat unreliable. Generally, push() does some extra bits of processing from the base JS object that arrays extend from, whereas using an index approach bypassing that little bit of overhead.

I'll add a comment about it in the method docs, because I think it should also explain why spread operators aren't being used.

It's hard for me to tell what is style and what is an improvement. Is there some benefit to declaring the object with all the properties it might have instead of assigning them later?

My reason for this change is that before, 100% of the logic was running regardless if there was a report or not. There is logic for reports AND personal details but for the LHN, we only need the logic for the reports. By being more strategic with the if statements, it now means that it only runs the minimum necessary logic depending on if there is a report or not.

That sounds intuitive to me. Mostly asking as I'm curious which of these changes had the biggest impact on performance (for my own understanding).

Yeah, I could have taken better notes while doing this, but in the end, I don't think there are hugely practical takeaways. At large scale, ANY piece of code can become inefficient, and the same thing that fixes one bottleneck isn't going to fix all bottle necks and shouldn't be used everywhere just for the sake of performance (like uniqFast()).

I think the better takeaway for anyone would be to learn how to do performance testing. This is something that I could do a LOU about because it seems like very few of our engineers are familiar with how to do this.

Just for a quick sample though, here were the notes that I did take:

getSearchText
before 59.8ms
after 39.2ms

createOptions
before 117.2ms
after 115ms
  • those times are the total amount of time those methods took during a report switch (which is like ~8 re-renders of the LHN)

The changes to getSearchText() were to stop using .push() and _.unique()

Yes! This came from me solving a merge conflict. isDefaultRoom didn't exist when I started refactoring so it got kind of left out.

Yeah, there are a few things here... _.each doesn't protect against null members in a collection, so it's possible for report to be null.

This particular line of code (and several lines down below it) need to have null protection. There are two solutions around this typically...

  1. Use _.compact for arrays to clear out falsy values or use _.pluck for objects
  2. Add an early return if report is null

I think I'm going to do number 2 and then remove all the report null checks

We probably could. I'm honestly a bit perplexed by this and the comment. Since reports are indexed in Onyx by their ID, I don't think it should ever be possible for a report to not have an ID. If it is possible, I think it is a bug that we should track down and fix. So, I'd be more willing to either remove this check entirely, or at least add a log if we detect there is no reportID.

Since reports are indexed in Onyx by their ID, I don't think it should ever be possible for a report to not have an ID. If it is possible, I think it is a bug that we should track down and fix.

I'm feeling cautious about removing that since it looks like we use the "report without a reportID" as a kind of "hook" to fetch the report. Which was the expected behavior at one point. But also looks like there's maybe some further cleanup to do here:

https://github.com/Expensify/App/blame/c9b41bff8b728073db85f38782b591a0fd4a9772/src/libs/actions/Report.js#L1135-L1137

We could solve this by sending the report and comment when a new message is added.

Still feeling cautious and agree we should try to figure out if/why a report object can be merged with no reportID (and a log would help)

About the best I can offer in that case then is to add a log somewhere to detect if a report ID is missing. I don't think this code is the right place for it though. I would add it somewhere in Onyx.update() probably? Something like:

if (key starts with "report_" and value has no reportID) {
    Log to the server
    return early
}

but that doesn't really work because of doing something like Onyx.merge('report_123', {reportName: 'blah'})

I kind of just feel here like we need to trust that we would never have a report without a reportID. And if it happens, we will find out about it in buggy behavior and crashes.
