A function can also hold a promise object directly and do other processing first (including ...
Several mainstream languages now have language support for futures and promises, most notably popularized by FutureTask in Java 5 (announced 2004) [21] and the async/await constructions in .NET 4.5 (announced 2010, released 2012) [22] [23] largely inspired by the asynchronous workflows of F#, [24] which dates to 2007.

Its features include exponentiation operator ** for numbers, await, async keywords for asynchronous programming (as a preparation for ES2017), and the Array.prototype.includes function. [5] The exponentiation operator is equivalent to Math.pow, but provides a simpler syntax similar to languages like Python, F#, Perl, and Ruby.
In functional programming, continuation-passing style (CPS) is a style of programming in which control is passed explicitly in the form of a continuation.This is contrasted with direct style, which is the usual style of programming.
