• JavaScript: Fix closure compiler typecasts ([#5947] by [@jridgewell])

  If a closing parenthesis follows after a typecast in an inner expression, the typecast would wrap everything to the that following parenthesis.

  // Input
  test(/** @type {!Array} */(arrOrString).length);
  test(/** @type {!Array} */((arrOrString)).length + 1);
  
  // Output (Prettier stable)
  test(/** @type {!Array} */ (arrOrString.length));
  test(/** @type {!Array} */ (arrOrString.length + 1));
  
  // Output (Prettier master)
  test(/** @type {!Array} */ (arrOrString).length);
  test(/** @type {!Array} */ (arrOrString).length + 1);

• JavaScript: respect parenthesis around optional chaining before await ([#6087] by [@evilebottnawi])

  // Input
  async function myFunction() {
    var x = (await foo.bar.blah)?.hi;
  }
  
  // Output (Prettier stable)
  async function myFunction() {
    var x = await foo.bar.blah?.hi;
  }
  
  // Output (Prettier master)
  async function myFunction() {
    var x = (await foo.bar.blah)?.hi;
  }
