-<a id="why-is-this-needed"></a>Unfortunately, prior to version 4.18, you couldn't simply `npm install` the ArcGIS API and `import` its modules. The only reliable way to load ArcGIS API for JavaScript modules was using Dojo's AMD loader. Rather than using Dojo to build your application, esri-loader provides a way to dynamically load modules at runtime from a hosted build of the ArcGIS API into applications built using modern tools and framework conventions. This allows your application to take advantage of the fast cached [CDN](https://developers.arcgis.com/javascript/latest/guide/get-api/#cdn).

+esri-loader provides a convenient way to lazy load the API in any application, and it has been the most versatile way to integrate the ArcGIS API for JavaScript with other frameworks and their tools since it works in applications that:
 - are built with _any_ loader/bundler, such as [webpack](https://webpack.js.org/), [rollup.js](https://rollupjs.org/), or [Parcel](https://parceljs.org)
 - use framework tools that discourage or prevent you from manually editing their configuration
 - use either version [4.x](https://developers.arcgis.com/javascript/) _or_ [3.x](https://developers.arcgis.com/javascript/3/) of the ArcGIS API for JavaScript
 - make very limited use of the ArcGIS API and don't want to incur the cost of including it in their build
 
-Most developers will prefer the convenience of being able to `import` from `@arcgis/core` directly, especially if their application makes extensive use of the ArcGIS API. However, if `@arcgis/core` doesn't work in your application for whatever reason, esri-loader probably will.

+- <a id="known-limitations"></a>Compatibility with implementations that don't support [async/await](https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Asynchronous/Promises#async_and_await) at runtime, within AMD modules, will be deprecated at version 4.25. In particular, Angular applications using esri-loader will need to migrate from AMD modules to using [@arcgis/core ES modules](https://developers.arcgis.com/javascript/latest/es-modules/).
