This chapter focuses on asynchronous backend OData calls. It shows how you can make your OData calls “Promise ready”.
Normal ECMAScript 5 Projects
Find out how to wrap your OData calls with Promises and make use of the Promise Chain feature.
Modern ECMAScript 6 Projects
Requires modern Browsers
If your project uses modern JavaScript, you can consume Promises using the Async / Await pattern and handle OData calls as if they where synchronous.
