What is ternary operator in Javascript

Here's an example:

let age = 25;
let result = age >= 18 ? "You are an adult" : "You are not an adult";

console.log(result);

In this example, if the age is greater than or equal to 18, the condition age >= 18 evaluates to true, and the ternary operator returns the string "You are an adult." If the condition is false, it returns "You are not an adult."
