Web based UI's (javascript baked in) are the only cross platform GUI all the major tech players endorse. Companies like Apple are hostile to alternative GUI frameworks, except web browser. Flash? that threatens the walled gardens so the big tech cartel came together to squash it out. Java graphics? we will not ship a JVM becuase "security". The web was already ubiquitous so the big tech couldn't squash it without squashing their own foot.

Typescript let's you start with a cross platform GUI right out of the gate. Text based HTML GUI is screen reader friendly, battle hardened for many years to get accessibility right.

Type system is advanced and allows for that sweet IDE experience.

And.... the Javascript ecosystem is the only game in town that gets close to the Lisp immediate feedback experience. (no Javascript is not as good as a lisp image, but it's better than nothing). Change a function, see the result instantly in the browser while you're app is still running. I'm not 100% sure this is true for Typescript as it must compile to javascript first, but compiling the TypeScript for 1 modified file with an on-save-hook could still be a pretty quick feedback loop.

Do these reasons have anything to do with AI agents? no but it would explain why people are already using Typescirpt, and thus use it for AI agents.
