F # can synthesize several function groups into new functions

What C # can do, F # basically can do, but what F # can do, C # may not be able to do.

The functions in F # can be used to combine several functions. The following example combines the two functions of function1 and function2 into Funuoction3 with the operator ">>" (or "<<"), which can then be used Function3.

Let function1 x = x + 1

Let function2 x = x * 2

Let Function3 = function1 >> function2

Let RESULT5 = Function3 100

The result of the operation is 202.

Let's look at the following example:

Let AddOne x = x + 1

Let timestwo x = 2 * x

Let Compose1 = AddOne << timestwo

Let Compose2 = AddOne >> timestwo

The result is 5.

Let RESULT1 = Compose1 2

The result is 6.

Let result2 = Compose2 2
