The Differences between ES6 Maps and Sets

preview_player
Показать описание
Maps are similar to Objects. Sets are similar to Arrays. Both provide you with Iterators which means that both can be used with a for...of loop.
Plain JavaScript Objects are not Iterable.
You can pass an Array directly into a Set using the constructor.
For Objects you need to loop through the properties and pass them to a Map one at a time.

Nice short video on the differences between Set/Array and Map/Object. I wanted to ask what are the purposes of using WeakMap and WeakSet? Only the advantage of garbage collection of the keys, am I right?

If you do an Array.from(names), you can convert the names Set back to an Array with duplicates removed. Quick way to eliminate duplicates from an Array.
