-In addition to the above formats, Microbundle also outputs a `modern` bundle specially designed to work in _all modern browsers_. This bundle preserves most modern JS features when compiling your code, but ensures the result runs in 90% of web browsers without needing to be transpiled. Specifically, it uses [preset-modules](https://github.com/babel/preset-modules) to target the set of browsers that support `<script type="module">` - that allows syntax like async/await, tagged templates, arrow functions, destructured and rest parameters, etc. The result is generally smaller and faster to execute than the `esm` bundle:
