Use Maps more and Objects less

#javascript #performance

[zacharyallen]

It's worth noting that "frequently" in the terms of the MDN docs means an insane amount - ie orders of magnitudes more than you'd need for most use cases. The inconvenience in using maps, and the gotchas around memory mean that they're usually just a premature optimization and not really a good thing to recommend to a beginner.

Just found accidentally your channel and based on the number of likes, I think you are way underestimated. Awesome videos, new subscriber here.

I am new in this channel and this video is really nice thanks :)

It's good to remember that maps are not JSON.stringified by default...
Also, the order of keys is the insertion order (so it's good for stuff like LRU cache)

Man your video came at the perfect moment!

Pretty Impressed by the content you make. Have a lot to learn, know and implement from your videos. Keep posting best practices. Tried to connect over LinkedIn too but asking email.

An awesome explanation and presentation

What I took away from it: Objects should be used to describe actual things (ie. real life objects, hence oop), maps are used as a collection of things where you need more functionality than an array
