JS just got RAII, welcome to the party

[DillonRedding]

This is such a great use case for symbols. They demonstrate how we can extend the language in a way that doesn't requiring classes.

[iiilllii]

WOW, this is cool. This is similar to C++ class destructor function.

[pouris]

honestly just introduce a defer keyword and have it work similarly to how go does

[FacuA]

Yeah, the same as the "with" keyword in Python or the "try ()" syntax in Java.

Kyle "The Dream Boat" never fails to amaze me. Thanks for the tip.

What benefits does using .open() bring? I never did it and called .readFile() or .writeFile() directly...

0:12 Is that a Windows thing, being unable to delete a file that some process has open?

This is a JavaScript limitation, that objects are not immediately disposed when they go out of scope. Python, for example, doesn’t have this problem (at least not as bad).

[vilijanac]

perl scope closes any handles, like file, stream, session

[scottstot]

Can you make a tutorial for Vitest unit testing or thunk/slice

[dferg]

Yeah but.. if you don’t remember to file.close() before, what makes you think someone is gonna remember to make a dispose function that calls it?

Link on description no longer clickable. Nice one yt

[LarsRyeJeppesen]

Surprised he did not add react hooks lol

[GreenZapperZ]

The link to the full video in the description does not work

[squdge]

Doesn’t feel intuitive for everyday use, but a nice cleanup callback that can live under an interface.

[naudos]

Isn't there something similar in Python?

[anafro_ru]

Hmmm :))
What if I...


using file = ...
return file

Will it stay forever?

[nghiaminh]

this seems to be a more server-side feature to me.

[misigarodev]

a try with resources in my old Java world 😊
