TypeScript 3.7 is finally here! ✔ Optional Chaining & Coalescing ✔ Assertion Functions ✔ .d.ts Emit From .js Files ✔ Smarter Control Flow Analysis ✔ Flatter Error Messages and more! Check out the blog post today! devblogs.microsoft.com/typescript/ann…
@typescript .d.ts emit from .js files?! Oh wow I need to check this out for @fastifyjs
@typescript @coderbyheart Guess who's gonna update some dependencies instead of fixing "urgent bugs" tomorrow.
@typescript I was waiting for optional chaining since migrating to JS from CoffeeScript in 2015! Thank god it is back in my life!
@typescript We celebrated Typescript release on our office at @realtordotcom
@typescript Amazing release! You all absolutely nailed it in DX this iteration. I think optional chaining and null coalescing are going to make strict mode an easier sell for people who were on the fence. Coupled with the better control flow analysis—this will help us write better code.
@typescript I forgot to mention recursive type aliases! I'm going to do so many horrifying things!
@typescript So excited about thee project reference navigation from source to source. Awesome for monorepos
@typescript We just updated API Extractor to support TypeScript 3.7. Help test it out by running it on projects with the new language features! @rushstack
@typescript I love how optional chaining (a JS feature) reuses❓to access optional properties at runtime that have been marked with❓in the interface (a TS feature) during compile time, great DX and foresight by the TS team!
@typescript I waited for optional chaining and nullish coalescing for so long. Great so see it's finally here and that you waited to be compatible to ECMAScript.
@typescript Can't wait to start using the Optional Chaining 💪 Very cool release!!
@typescript Did ts.DiagnosticMessageChain.next change to be an array in 3.7?
@typescript @DeborahKurata Can’t wait till tomorrow to use some of this new features
@typescript @typescriptlang In a project, I need to use a plugin of a 3rd party library, which has no typings (.d.ts file). How is it possible to create it by myself preferably automatically? Any link to best practices/tutorials will be also helpful...
@typescript @mrwolfgio agora talvez faça sentido migrar pra TS. Optional chaining nativo
@typescript Very very great update ! Optional Chaining & Coalescing 🥰🥰💪
@typescript While upgrading API Extractor, @kevintcoughlin found that TS 3.7's typescript.d.ts produces compiler errors with TS 3.1 used by our toolchain. Syntax error for "readonly" arrays. It's a potential compatibility issue for any .d.ts files that import compiler types. 🤔Worth fixing?
@typescript @ausginer > .d.ts Emit From .js Files This means TypeScript is part of my toolchain now. Great stuff!
@typescript I upgraded but using Optional Chaining doesn't seem to be recognised by VSCode/tslint yet. It's underlined in red :-( Have I missed something?
@typescript .d.ts from js files o:
@typescript Optional chaining will part of ES10. But we can using this now! Thanks @typescript
@typescript @SeaRyanC Love the new code golf features! <3 I found a small mistakes in the release notes: github.com/microsoft/Type…
@typescript Good morning everyone, I would like to report anomalous behaviour: When they use ForEach to populate an array, we don't actually populate an array with n elements but an array with 1 element with an array with n elements inside.
