It'd be really nice if lazy values made it into the spec somehow. I've already found myself using things like this [1] quite a bit, and I've also found myself frequently initializing properties not on first access.
[1]: https://gist.github.com/isiahmeadows/4c0723bdfa555a1c2cb01341b323c3d4 As for what would be a nice API, maybe something like one of these? ```js class Lazy<T> { constructor(init: () => T); get(): T; // or error thrown } function lazy<T>(init: () => T): () => T; // or error thrown function lazy<T>(init: () => T): { get(): T; // or error thrown } ``` Alternatively, syntax might work, with `do` expression semantics: ```js const x = lazy do { ... } // expose via `x.get()` or just `x()` ``` ----- Isiah Meadows [email protected] Looking for web consulting?
