Re: Would it be possible to add “await on first use” to the language?

So you'd be imagining something that would create a variable that would automatically await when accessed, like ``` async function makePizza(sauceType = 'red') { await const dough = makeDough(); await const sauce = makeSauce(sauceType); await const cheese =

Re: Would it be possible to add “await on first use” to the language?

To clarify, the idea is to declare and kick off all the concurrent tasks upfront (using local variables and the ‘lazy await’ keyword), and then just continue writing the rest of the code ‘as if all the promises are resolved’. The async function automagically pauses whenever needed, so it’s no

Proposal: a more consistent and stricter number converting function - Number.of()

Hi, Converting an arbitray value to a number in JS can be rather inconsistent and unexpected: * `null` and `undefined` are different: `+null === 0` but `+undefined` is NaN. * Empty string and non-nubmeric strings are different: `+"" === 0` but `+"foo"` is NaN. This problem can be

RE: Would it be possible to add “await on first use” to the language?
