In computer science, future, promise, delay, and deferred refer to constructs used for synchronizing program execution in some concurrent programming languages . They describe an object that acts as a proxy for a result that is initially unknown, usually because the computation of its value is not yet complete.

Read moreWhat is a Future string?
For example, if a function returns Future<String> , this means that in the future, it will provide a string to you . For the sake of practicing, we can use one of the Future constructors to create our own Future object. The following code creates an instance of Future<String> which will complete immediately.
