Flow Control
Explore the various flow control mechanisms in Clojure including conditionals, logical operations, and variable binding with the let function. Understand how these tools help in writing clear, concise, and reusable functional code, supporting multiple validation options and complex branching to manage program flow effectively.
We'll cover the following...
The clojure.core library also has a group of functions that we’ll use in this course to build our flows. As in any other programming language, we need to use conditionals, store values for future use, validate stuff, and sometimes include more than one possibility.
Validator’s helpers
One of the most commonly used functionalities that we normally assume any language will cover for us is the possibility of delivering more than one validation using logical and and or operations. Clojure not only has these functionalities but also treats them as functions themselves, so they may have two different usages:
Function as validations that return a boolean and might be combined with a conditional flow
Return their actual value, which in the
andfunction will be a boolean, and in theorfunction might be whichever value it contains ...
