Steve - I'd like to say as a beginner, I'd love for you to make a full beginner to advanced JavaScript course, you are a really good teacher.

Kindly think about it

Are you using ChatGPT to write these? You're pumping them out so quick haha

Also it would be awesome if you did one on the WeakSet and Blob constructors.

Love the content!

Nice content, can you tell me from where does to performance index you are deriving from

When we try to set same object with same value in a Set. Will Set do its thing and only store unique value of that object

When does the order of elements not matter in an array? Can you give an example of where to use this?

Hi love your channel and all the performance tips you share. I was wondering, sets or enums in typescript since it would still transpile to JavaScript? 🤔

In which situation does it make sense to use a Set of objects?

[robottrainer]

performance is the only advantage, you can't use any es6 functions to filter, find, some, etc. to arrange, edit, or any complex arrays with many levels.

Seems like using an object with extra steps.
