## E0061: missing name in function statement

If a statement begins with the `function` keyword, the declared function must have a name. It is an error to start a statement with `function` but not give a name to the function:

    function (number) {
      return number % 2 === 0;
    }

To fix this error, write the name of the function after the `function` keyword:

    function isEven(number) {
      return number % 2 === 0;
    }
