Hello all,
I frequently find myself desiring a short array or generator
comprehension syntax. I'm aware that there are functional ways around
use of comprehension syntax, but I personally (at least) love the
syntax in the ES reference
(https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Array_comprehensions).
The best previous discussion on this that I found was six years old
(https://esdiscuss.org/topic/array-comprehensions-shorter-syntax) and
answers some of my questions, raising others. That said, I wanted to ask:
* Why is the Comprehension Syntax in the reference yet not more
standard? It feels almost like a tease.
Proposals to change the standard are listed here :
https://github.com/tc39/proposals
The process for a feature to become standard is described here :
https://tc39.github.io/process-document/
* How do you usually approach or avoid this issue?
* Do you think we should look at improving and standardizing the
comprehension syntax?
Some might argue it is yet another instance of "superficial sugar
obsession" [1] :-p I don't know where I stand personally.
In any case, if you want to start, write down a proposal (can be 20
lines in a gist [2]) including programs that are hard to express in
JavaScript and which readability would significantly be improved with
the new syntax.
Perhaps submit it to the mailing-list and try to find a "TC39 champion"
(criterion to enter stage 1).
At the very least, the proposal will be listed in the stage 0 proposals
list [3].
