Casting to 'const' should work as const assertions in TypeScript typically works. I.e. that code shouldn't fail.

You should enable --loader=ts to tell esbuild the input is in TypeScript (default is JavaScript).

Yes, compiling TypeScript as JavaScript is expected to not work on TypeScript-only syntax. Compiling TypeScript as TypeScript works as expected.

I'm closing this issue as this is not a bug with esbuild.

evanw closed this as not planned
