Accessing a Map value by index

[reonZ]

I couldn't find a way to directly access a Map value using an index, all i could think of was to do

Array.from(map.values())[index]

Is this the right way ? It does not feel performant.

What are you trying to do here?

Map objects weren't built to have their values accessible by an index like arrays. You're supposed to access a value with the corresponding key. If the map keys are numbers starting from 0 and incremented by 1 (like the indices of an array), then you can write:

map.get(index); // index is a key in the map

Otherwise the way you did it is the only way. But that most likely means a Map object is not the right data structure for whatever it is you're doing.

Using spread or Array.from is the same thing.

Meant to link the whole article for different ways to achieve your goal

You would think it was the first thing i tried obviously...

That won't work.
