Do you know how to use the ternary operator in JavaScript?

Throughout the development process, there are various tools that we may be unaware of, or even know but choose not to use due to fear of making a mistake, or just simply not wanting to use it.

However, the ternary operator is an option for writing conditional expressions in a concise and efficient way. It is often used in else-if situations, where there are only two possible conditions.

The syntax for the ternary operator is as follows:

“Condition ? Expression1 : Expression2”

Here, the “Condition” is evaluated as true or false. If the condition is true, then Expression1 is evaluated and returns the result. If the condition is false, then Expression2 is evaluated and returns the result.

For example, let’s say a student took a math test and needs a score greater than 7 to pass. Otherwise, they fail. How can we represent this using the ternary operator?

var studentScore = 8;

var evaluation = studentScore > 7 ? “Pass” : “Fail”;

console.log(evaluation); // output: “Pass”

In this case, the condition is “studentScore > 7”, which is true, so the Expression1 “Pass” is returned and assigned to the variable “evaluation”, resulting in an output value of “Pass”.

The ternary operator can make the code cleaner and more readable in situations where there are only two possible options. However, in situations where more conditions are required, it is better to use the good old else-if.

I hope this post can help you understand and use the ternary operator better, as it has been a great learning tool for me! :D
