I hope the pace will accelerate. The real questions is what functions we need though. Some candidates that I would love to see are better helper functions on iterators, and Uint8Array<->base64/hex. Most of the "standard library" in most languages is related to IO, and for JS is dependant on the host (the web, Deno, Node) so not something TC39 will touch directly. Do you have ideas for standard library functions that you think are missing?
Range a-la python is a generator and is pretty straightforward in js as is. There is no need for a complicated solution and/or as part of stdlib, imo:
function* range(x, y) {
while (x <= y) {yield x++}
// or ‘<‘ if you want half-open one
}
for (let n of range(3, 5)){
console.log(n)
}
array = [...range(3, 5)]
console.log(array)
It's also straight forward to implement in python. It is common enough to be standard so people won't reinvent the wheel. And it should be available to people learning the language before they learn generators.
Array.prototype.indexOf is also pretty simple as are many core functions.
Nice, I didn't know about that, but in any case note that IMO it should be part of the Iterable protocol. Also note that the proposal above creates a copy on reverse AFAIKT.
