I would love some real-world use cases for Rest as well. I rarely use it but I feel like thats because I lack enough understanding. Same goes with Switch though, I need to just use them more lol

I try to stay up with new web platform features. Web feature you don't understand? Tell me! I'll write an article!

I find rest parameters super useful for writing wrapper functions. For a super simple example, I often like to define small logger functions as wrappers around console.log() that always add certain context, such as a label that tells me where the log was issued:
This is a pretty trivial example, but I've used it for much more complicated cases where I basically always use the same default arguments for calls to library functions with lots of arguments, and I want a wrapper that supplies all but the last couple arguments for me. I'll write a wrapper that gathers arguments into a rest array, then spreads them into the end of my call to the library function, like I did with console.log above

Noted! Maybe I'll get to those in the future.
Awesome! Thank you for listening to my suggestion!
