Conditional Logic

What is Conditional Logic in Programming?

Every programming language comes with the ability to use conditional logic.

To put it simply, applications frequently use if and else statements.

There are unlimited possibilities with this simple concept.

Basic example of conditional logic in websites

Suppose you have two different footer styles for your website. With a different footer layout on your website’s homepage.

You could use conditional logic to achieve this. Using your language of choice, you would write something that translates to:

if: page = homepage     
  render "homepage-footer" 
  render "default-footer"

Basic example of conditional logic in an application

if: user = (loggedin)
  render "account-page"
  render "login-page"
