alt Hacker NewsThe desire to keep things compatible with even ES6, let alone ES5 and before, is utterly bizarre to me. Then you see folks who unironically want to maintain compatibility with node 0.4, in 2025, and realize it could be way worse....
Ironically, what often happens is that developers configure Babel to transpile their code to some ancient version, the output is bloated (and slower to execute, since passes like regenerator have a lot of overhead), and then the website doesn't even work on the putatively supported ancient browsers because of the use of recent CSS properties or JS features that can't be polyfilled.
I've even had a case at work where a polyfill caused the program to break. iirc it was a shitty polyfill of the exponentiation operator ** that didn't handle BigInt inputs.

It's just an excuse to not change things.
Just how old an Android device in the developing world do you not want to support? Life's great at the forefront of technology, but there's a balancing act to be able to support older technology vs the bleeding edge.
I’ve been very lost trying to understand the ecosystem between es versions , typescript and everything else. It ends up being a weird battle between seemingly unrelated things like require() vs import vs async when all I want to do is compile. All while I’m utterly confused by all the build tools, npm vs whatever other ones are out there, vite vs whatever other ones are out there, ‘oh babel? I’ve heard the name but no idea what it does’ ends up being my position on like 10 build packages.
This isn’t the desire of people to build legacy support, it’s a broken, confusing and haphazard build system built on the corpses of other broken, confusing and haphazard build systems.
Maybe I didn't look hard enough, but there's no obvious switch to "just turn off all the legacy stuff, thnx".
Also, there has been a huge amount of churn on the tooling side, and if you have a legacy app, you probably don't wanna touch whatever build program was cool that year. I've got a react app which is almost 10 years old, there has to be tons of stuff which is even older.
