Do you really know how to use a Map in Javascript? 🤔 #javascript #map #datatypes #tutorial

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

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

[ajithm]

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

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

"Map through?" "Iterate through"
