TypeScript 6.0 is now available, drops ES5 support in an end of an era
Posted: (EET/GMT+2)
Great news for all TypeScript fans out there: Microsoft has just announced the availability of TypeScript version 6.0. Once again, this release packs many new features, including better this handling, subpath imports, Temporal proposal support (finally, JavaScript!), and "upsert" methods, to name a few.
But, I find it even more interesting what gets deprecated and no longer supported. On top of this list, it's ECMAScript 5 support. Surely almost no one is needing ES5 in any modern web application anymore, but even so, this is a significant point in time: you can no longer target with -t or --target options ES5 from 2009 with TypeScript 6.0.
I don't mind using newer JavaScript versions, as I'd guess most web developers today, but even so, it's an end of an era. Roughly speaking, it took about 17 years.
Go TypeScript! (With the pun: TypeScript's compiler is now Go-based!)
