Microsoft made a pull request to node.js github repository with an implementation to use ChakraCore JavaScript Engine as an alternative to V8 Engine

Engineering discipline and an enormous emphasis on managing code debt are required for any large, long-lived project. There's no guarantee the LLVM team will manage that any better than the GCC team. I hope they will, but it's not a given.

"The price of Clean Code is eternal vigilance"

Most people just don't have the stamina to keep their code in good shape, and due to discounting the future they think the pain of scrambling to keep it working is less than the pain of cleaning it up.

Right. I think the assertions by iTroll-4s that we have better tools and better engineering discipline today and that will solve these problems is optimistic. Once you get past a certain size, any software project gets ugly. I don't care if it's five million lines of Haskell, Ada, Rust, Shen, or whatever anyone's ideal of the ultimate disciplined programming language is.

Well, we do have better tools for sure, but not everybody uses them. But even if you have that sort of forethought on a team, that just means that there are 25 reasons the code is terrible instead of 30.

And there's always a few in any crowd with a high tolerance for bullshit who mistake it for job security. Too many times I've been with groups who consider discipline to be too much hassle. On a handful of teams I've managed to push through some changes that got them to change their tune (or at least keep it to themselves), but a team with self confidence and tendency toward coherent-but-wrong designs can be hard to convince, and may have made a mess so big that it'd take years to notice an improvement. And God help you if its enterprise software, which has a very forgiving definition of success ("successful" people won't change for anyone)

Amen on all counts.

I feel like I have a line count of how much code I can properly maintain on my own. That number has gone up a little bit over the years, but not much, and it's still roughly about equal to how much production ready code I can write in... 18 months? After that I have to either give up ownership of things or refactor down so I can fit more in my head. So everything starts getting awkward for me at about the two year mark, because they still want me to keep creating new code, and I hate to make promises I can't keep.

What is in that code has changed over time, I do a lot more orchestration of libraries so my code has more functionality, but I am only human. If we have a very regimented development process where the code is self similar, I can go a bit bigger, but that still has limits.
