Web3. Continuation Passing Style (CPS) 3.1. Simple CPS CPS is a programming style in which the successive function(s) that uses the result of current function is given as an argument of the current function. [code 1] shows adding and multiplying written in CPS. In k+ and k*, k is the successive function.

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. Gerald Jay Sussman and Guy L.
