# Bridge ** Don't include any ES6 syntax in js underneath bridge folder, IE doesn't recognize it.

The `bridge` directory is a means to bridge the gap between ES6 modules and AMD modules. AMD modules are used for a number of reasons:

- Since CA was originally based on AMD modules, the API expects to be able to load AMD modules.
- Lazy loading third party libraries.
- Lazy loading localization.
- Reuse of legacy MUI code.
	- All of this code should eventually be eliminated.
