E0068: extra ',' is not allowed between function call arguments

In a function call, an extra , can be added to the end of the argument list. However, it is a syntax error to include an extra , in between arguments:

let name = prompt();
console.log("Hello",, name);

To fix this error, remove the extra ,:

let name = prompt();
console.log("Hello", name);

Alternatively, write an argument between the two ,s:

let honorific = prompt();
let name = prompt();
console.log("Hello", honorific, name);

Introduced in quick-lint-js version 0.2.0.
