🕗 Version

latest 0.14.48

💻 Code

// bar.ts
export const enum PRCD {
	"*/%" = 14,
}

// foo.ts
import { PRCD } from "./bar";

console.log(PRCD["*/%"]);

esbuild foo.ts --bundle --outfile=foo.js

🙁 Actual behavior

"use strict";
(() => {
  // foo.ts
  console.log(14 /* */% */);
})();

  console.log(14 /* */% */);
//                      ^^ ERROR: Unterminated regular expression literal. ts(1161)

🙂 Expected behavior

No errors

Interesting, I haven't seen this behavior in transform mode because it removes comments. TypeScript used to have this issue too but they have fixed it in 4.7 with a simple string-replacement: */ → *_/. (see more about that at microsoft/TypeScript#47990)
