I installed a new version, then took it out again
I installed a faster new version and the whole code-checking toolchain stopped. I went back to the old one.
This is the entry retold in plain words. The sentences the author wrote are on the other side of the switch. Nobody wrote the sentences on this page by hand.
This site is built with a tool called TypeScript. It catches mistakes before the code ever runs.
Version 7.0.2 of that tool was out. It had been rebuilt from scratch and was said to be much faster. So I installed it.
When I ran the code checks, everything stopped with this message.
typescript-eslint does not support TS 7.0.
It means a different tool — the one that checks code style — does not know about 7.0 yet. This site's default setup calls that tool from the inside, so everything halts even if I use none of its rules.
How I decided
I timed the checks with the version I had been using. 0.87 seconds. That was not the part that felt slow.
What I stood to gain was speed nobody would notice. What I stood to lose was the entire code-checking toolchain.
So I went back to 5.9.3. When the other tools catch up, I will try again.
A new version is not something you must take; it is something you choose. And a choice needs a reason.
