Browsers that understand type=”module” ignore scripts with a nomodule attribute. This means you can serve a module-based payload to module-supporting browsers while providing a fallback to other browsers. The ability to make this distinction is amazing, if only for performance! Think about it: only modern browsers support modules. If a browser understands your module code, it also supports features that were around before modules, such as arrow functions or async-await. You don’t have to transpile those features in your module bundle anymore! You can serve smaller and largely untranspiled module-based payloads to modern browsers. Only legacy browsers get the nomodule payload.
