If Ternary in JavaScript

As a programmer, you may have come across the need to write a conditional statement that needs to be converted into a single line for better readability and organization of code. This is where the ternary operator or conditional operator comes in handy.

What is If Ternary in JavaScript?

The ternary operator is a shorthand way to write an if-else statement in a single line. It is also known as the conditional operator because it evaluates a condition and returns one of two possible values based on the result.

The syntax for the ternary operator is as follows:

condition ? value1 : value2;

The condition is the expression that is evaluated to true or false. If the condition is true, the value1 is returned; otherwise, the value2 is returned.

Example

Let's consider an example where you want to check if a person is eligible to vote based on their age.

const age = 18;
let eligibility;

if (age >= 18) {
  eligibility = "Eligible to Vote";
} else {
  eligibility = "Not Eligible to Vote";
}
console.log(eligibility);

This can be written in a single line using a ternary operator as shown below:

const age = 18;
const eligibility = age >= 18 ? "Eligible to Vote" : "Not Eligible to Vote";
console.log(eligibility);

Benefits of If Ternary in JavaScript

Using the ternary operator has several benefits when compared to traditional if-else statements:

• It makes the code more concise and readable.
• It helps in reducing the number of lines of code.
• It is a faster way of writing conditional statements.

In this guide, we learned about the ternary operator in JavaScript and how it can be used to write a conditional statement in a single line. We also saw examples of how ternary operators can help reduce the number of lines of code and make it more concise and readable.
