In case you want to clear the entire array, you can do array.length = 0; it's performant

Correction, it is not. Don't do it.

Just a word of advice never used splice inside redux or any other J's state management system

Can we combine it with FindIndexOf to just remove the element without knowing it's index

Are you using any vs code extension for showing the missing semicolon.can you make a video on what extensions you are using?

What if you want to delete negative numbers? And numbers are not in order. What would you use? Regex?

johnddonnet

And then you can use Second argument 0 to not delete, but insert at exactly after the index in argument 1

Can you tell me name of the extension for sintax errors?

Or just `numbers.length = 2`.

It does the same, but I do not have to google the docs to know, what the resulting array will look like.

One thing I like to do when I have a list of indices to remove from an array is I do indices.sort().reverse() and then I can iterate through them in a for loop and delete them all in one go

Please, forgive me for this silly comment, but mention “inside the splice callback…bla, bla, bla…” But, which callback are you referring to? Splice gets parameters, not callbacks.

A bit of malicious compliance maybe 😂. Still good to know though 💪
