that Google/Oracle lawsuit settled pretty clearly that apis can be copied and reimplemented freely. this is just that but automated

knowing the programming language you’re working in at a basic level is gatekeeping I’m ok with

semicolons? quotes? use a formatter and don’t think about it. I think js world has basically done this already.

const is simpler. why would I declare an array as let if I’m not reassigning? someone can look at it and know they don’t have to think about reassignment of the reference, just normal mutation. ts has the further readonly to describe the other type of mutation, don’t abuse let to mean that.

const arrow over named function? gets rid of all the legacy behaviors and apis. no arguments, consistent this, and no hoisting or accidental reassignment. the 2 places you should ever use named fn are generator or if you actually need this
