Conditional if...else Statements

Published on: November 5, 2016

Welcome to the twentieth Easy JavaScript tutorial, part of EasyProgramming.net. In this tutorial, we will take a look at a way you can implement logical workflows in your code by using conditional statements. The particular statement we'll be covering is the if...else statement.

The if...else statement will allow you to create custom workflows for your users by setting conditions. When a certain condition is met, a specific part of the code is executed, and if another condition is met, another part of the code is executed. This is one of the few times you can actually speak in pseudo code and actually make sense.

I would also recommend that you check out my "if" statement tutorial in C++ to get even more practice and a better understanding of how the statement works. The syntax is the same!

Let's take a look at the Syntax of the if...else statement:


  if(condition is met){
      execute this piece of code;
    
  } else if(this condition is met){
      execute this piece of code;
    
  } else if(this condition is met){
      execute this piece of code;
    
  } else {
      execute this piece of code if no other condition is met;
  }
