Not Javascript. If I forget a var or let, it's global.

  Strict mode throws an error on implied globals. Use of modules forces strict mode.

    And that's all "extra" syntax.

      strict mode is the default in everything now and had been for many many years.

        It isn't the default for a browser "<script>" tag.
        • xigoi 6y ago
          It's the default for <script type="module">, which you should use anyway for anything serious.
