If you enjoy this tutorial, you may want check out my website at for more JavaScript goodies.Īlso, I have a free weekly newsletter about web development tutorials (mostly JavaScript related). I hope it has helped you to understand how the ternary operator works. It's best to stick with either if/else or switch statements for such cases. However, it's not recommended to replace multiple if/else statements with multiple ternary operators because it makes the code harder to read in the future. Here's one way to write the program: let score = 85 Ĭonsole.log(`Your exam grade is $`) Multiple ternary operators in action When you have a score higher than 80, you assign 'A' as the grade.In this case, we are telling R to multiply variable x1 by 2 if variable x3 contains. Let's say you have a small program that assigns different exam grades depending on your exam score: Multiple If Else statements can be written similarly to excels If function. To understand how it works, let's compare it with a regular if/else statement. If the expression returns true, JavaScript will execute the code you write on the left side of the colon operator ( :) when it returns false, the code on the right side of the colon operator is executed. The syntax for the conditional operator looks like this: conditional ? expression_when_true : expression_when_false conditional operator basic syntaxįirst, you need to write a conditional expression that evaluates into either true or false. The conditional operator – also known as the ternary operator – is an alternative form of the if/else statement that helps you to write conditional code blocks in a more concise way. This tutorial will help you learn how to replace an if/else statement with a more concise shorthand syntax called the ternary operator.
