Why use one of the trashiest languages, when we have so many good and effective languages outside of web browsers?

One man’s trash is another man’s treasure.

Come on, I also use JS for web, it doesn't mean I have to love it. Even it's creator admits low quality of his creation - it was made in a hurry. Try to be objective - if not monopoly in web browsers, JS would never exist or gain popularity.

modern js and ts are very usable plus you get access to a huge ecosystem.

Modern TS is usable, agree. But I'm talking about non-browsers world, where we have not just "usable" languages, but languages with much better characteristics, much better suited for the Embedded Systems. And they have even bigger ecosystems.

Who said _you_ have to love it? Some people do love JS. Those people will appreciate using it in embedded systems.

This isn't about C++.

ECMAScript has garbage collection.

What's the worse case latency of said garbage collection and how many embedded use cases does that preclude?

Well, the worst case of not having garbage collection is crashing due to memory leaks.

So tell me... is predictable latency worse than a hard crash?

Hard real time stuff generally doesn't leak because they statically allocate the at rest data and stack allocate the intermediate data.

Hard real time stuff also is, by definition, broken code if you can't reason about worse case latency.

Then why Java programms still have memory leaks?

The most significant form of garbage collection in the ECMAScript community is called npm.

Funny joke, but I have doubts about garbage collector in the world of Embedded Software.

Embedded spans a lot of different usecases and requirements. For lots of things a garbage collector is a non-issue. Not everything has hard realtime requirements.

Flawed one, it failed to collect itself.
