Steps to Reproduce:

1. create a file, copy the following code and paste it. select javascript mode

function func1(word1) {
  return word1;
};

func1("hello world");

2. Inspect TM scopes

Does this issue occur when all extensions are disabled?: Yes

brackets are punctuation when define function

brackets are meta when call the function

I test this basic code in other languages like golang, ruby. brackets are always punctuation instead of meta.

Should JS function bracket be meta instead of punctuation when calling the function?

Start by reproducing the issue in VS Code with the JavaScript snippet from the report, using Inspect TM Scopes on the function call brackets. Compare those scopes with the brackets in the function declaration and determine the intended classification; done means the grammar behavior is resolved and verified against this reproduction.
