incorrect parse of parenthesized array literal #2375

Closed

Shortest test case:

0?([]):1;

Test:

% npx esbuild@latest test.ts --outfile=test.js --platform=browser --target=es5
✘ [ERROR] Transforming destructuring to the configured target environment ("es5") is not supported yet

   test.ts:1:3:
      1 │ 0?([]):1; 
        ╵    ^

The carat is pointing to the open square bracket

The error is elicited by the ternary expression when the truthy part is a parenthesized array, irrespective of the number of elements.
