Let’s take a look at JavaScript conditional statement structure and syntax to get a better grip on how it works.
If it’s Monday, Tuesday, Wednesday, Thursday or Friday, you’ll need to wake up at 7 a.m., otherwise, you can wake up any time you’d like. The conditions in this example would be pretty simple: Let’s also imagine that you needed to wake up two hours before 9 a.m to arrive to work on time. Let’s imagine you had a job that required you to arrive at work by 9 a.m. In the language examples above, the condition would be the user’s language preference, and the action to perform would be to display the content in the preferred language.Īnother way to think of a conditional statement is to compare it to how you’d make a decision about what time you’ll wake up.
the action to perform once the condition is met.A conditional statement really has only two parts: The best part? You aren’t limited to a single condition, you can repeat this approach for any number of conditions - if the user prefers German, display the page in German, if they prefer Russian, display it in Russian.Īn interesting thing about conditional statements is how simple they are. What is a JavaScript conditional statement?Ī conditional statement tells JavaScript how it should behave when a certain condition is met.įor example, if a user visits your website and their preferred language is French, you could use a JavaScript conditional statement to determine the user’s preferred language is French, and then display the content of your website in French to them. Specifically, it will help you understand conditional statement syntax and how to write and use conditional statements. This guide will help you understand conditional statements in the JavaScript language. And this adds a powerful layer of sophistication to any JavaScript program. In a way, conditional statements give intelligence to your programs. Whether you want your program to decide the best time to ask a visitor to subscribe to your newsletter or display your site content in a different language, conditional statements will allow your JavaScript program to make decisions based on conditions and then act on them. One of the most incredible powers you can give to your JavaScript program is the ability to make decisions on its own.
