Do you really know how to use a Map in Javascript? 🤔

[@rajfekar4839]

map object 💙

[@userou-ig1ze]

I don't really get why a object or array is any less useful. looping through a map seems more tedious

[@jimmy3797]

well, the point is so that you just run map.get(0) and get the value of zero so you don’t have to loop at all

I like Map and Set instances, the problem comes when you need to serialize values

"Map through?" "Iterate through"

[@ajithm3804]

is it like a hashmap, i mean is the lookup time is constant?

[@pb8655]

It’s using a hashmap under the hood so yea the look up time is very efficient. Has alot better performance than the standard js object

[@goldmikanik8274]

Why I would Map instead of array? Not convinced, unless performance is better 🤷‍♂️
