## E0184: missing 'if' after 'else'

In an `if`-`else if`-`else` chain, it is a syntax error to omit the `if` keyword after `else`:

    function lastName(name) {
      let parts = name.split();
      if (parts.length === 2) {
        return parts[1];
      } else (parts.length === 1) {
        return name;
      } else {
        throw new Error(`unexpected name: ${name}`);
      }
    }

To fix this error, write `if` between `else` and the condition:

    function lastName(name) {
      let parts = name.split();
      if (parts.length === 2) {
        return parts[1];
      } else if (parts.length === 1) {
        return name;
      } else {
        throw new Error(`unexpected name: ${name}`);
      }
    }

Introduced in quick-lint-js version 2.0.0.
