You have to check students' grades based on their marks, and you only have to check whether the student has passed or failed. Imagine that you are the class teacher for grade 5, class C. Let's take a simple example to understand how this works. If the condition is false, then the else statement executes a different code block. If the condition is true, then the if statement executes a specific code block. If-else statement takes a specific condition and checks whether the condition is truthy or falsy. The if-else and else-if statementsĪs newbies, we all love if-else statements! 😂 If you want to refresh your memory on how the conditional works, check out this MDN article. So if-else and switch-case both allow us to make these decisions based on a condition. If the condition is true, we can perform one action, otherwise, we can perform a different action. For example, if we have some free time, we have to decide what to do, whether to rest, watch something, call someone or maybe do something productive.Ĭonditional statements allow us to make such decisions based on a condition in JavaScript. In this article, I will explain these two concepts and provide a comparison chart, so you will understand how you can use if-else and switch-case in different scenarios according to the complexity.īefore jumping into details, let's refresh our memory on why we use conditional statements in our programs.Īs human beings, we make various decisions all the time that affect our lives. I struggled over understanding the difference and application of these two conditional statements and dug deeper into the topic. But then, when I learned more about this topic and tried to apply it to some problems, I got confused about which one I should use, what's the exact difference, and how I should choose the correct one. When I first learned about conditional statements, I thought it was simple enough, and I could use either if-else or switch in any case.

Users can see the example of too many if-else here.If you are a newbie to programming and JavaScript, you might be confused about which conditional statements to use, especially between if-else and switch-case statements. Suppose that in the code, you apply too many conditions to the if-else statement it will become complicated. The switch-case statement is the advanced version of the too many complicated if-else statements. In this tutorial, we will learn to come out of a switch case in JavaScript.
