Hi @karlhorky, is it okay if I create an npm package for that with tests?
You're free to take the code and publish a package :) Just be aware, there are a number of very similar packages already:
- https://www.npmjs.com/package/try-to-catch
- https://www.npmjs.com/package/@casperengl/try-catch
- https://www.npmjs.com/package/try-catch-js
- https://www.npmjs.com/package/trycatch (closest to ES Proposal, also supports synchronous mode)
- https://www.npmjs.com/package/await-to-js
- https://www.npmjs.com/package/try-catch-expression
- https://www.npmjs.com/package/try-catch
- https://www.npmjs.com/package/try.catch
TS 4.4 may no longer "forget" the type information after destructuring: https://twitter.com/sebastienlorber/status/1409543348461965314?s=19
Ok, this is true for a single variable, but it doesn't apply for multiple variables being destructured: https://stackoverflow.com/a/59786171/1268612
It looks like this is actually a separate feature request called "Correlated Unions" by jcalz here: microsoft/TypeScript#30581
Seems like this may be in TypeScript 4.6, since this PR got merged:
Thanks @karlhorky
