Ternary Operator

The ternary operator is a concise way to write simple conditional statements. It provides a compact syntax for making decisions based on a condition.

Syntax

The syntax for the ternary operator is as follows:

1condition ? expression1 : expression2;

The condition is evaluated and if it is true, expression1 is executed. If the condition is false, expression2 is executed.

Example

Consider the following code snippet:

1let age = 25;
2let greeting = (age >= 18) ? "Welcome, adult!" : "Sorry, you must be 18 or older.";
3console.log(greeting);

In this example, we use the ternary operator to check if the age variable is greater than or equal to 18. If it is, the value of greeting will be "Welcome, adult!". If not, the value will be "Sorry, you must be 18 or older.". The result is then printed to the console.

The ternary operator can be nested, allowing for more complex conditions and expressions. However, be cautious not to make it too complex, as it may reduce the readability of your code.
