E0118: unexpected 'finally' without 'try'

try statements can have a finally clause. It is a syntax error to have a finally clause with no corresponding try statement:

let recursionDepth = 0;
function recursionExample() {
  if (recursionDepth > 100) {
    throw new Error("too much recursion!");
  }
  recursionDepth += 1;
  try {
    recursionExample();
  };
  finally {
    recursionDepth -= 1;
  }
}

To fix this error, make sure the finally keyword immediately follows the } for a try block or a catch block:

let recursionDepth = 0;
function recursionExample() {
  if (recursionDepth > 100) {
    throw new Error("too much recursion!");
  }
  recursionDepth += 1;
  try {
    recursionExample();
  }
  finally {
    recursionDepth -= 1;
  }
}
