To get more specific, lets build up some motivation and consider the following compose function: compose then returns a function which feeds its argument through f and then g. When calling this function, TypeScript will try to figure out the types of A, B, and C through a process called type argument inference. Improved behavior for calling union types. However, in TypeScript 3.3 and earlier, generic functions like compose didnt work so well when passed other generic functions. The problem is that the more objects you want to create, the more duplicate code you have. Classes are a template for creating objects.
