How to use Prompt function in JavaScript ?

In this tutorial we’re going to learn how to use Prompt function using JavaScript.

  • let age = prompt("What is your age?", 18); – This line of code uses the prompt() function to prompt the user for their age. The second argument, 18, is the default age if the user does not enter anything.
  • let welcome = (age < 18) ? () => alert('Hello!') : () => alert("Greetings!"); – This line of code creates a variable called welcome and assigns it an anonymous function. The anonymous function takes one argument, age, and returns a function that displays a message. The age < 18 expression inside the ? ternary operator checks if the user’s age is less than 18. If it is, the first function is returned. Otherwise, the second function is returned.
  • welcome(); – This line of code calls the welcome() function. This function will display the message “Hello!” if the user’s age is less than 18, or the message “Greetings!” if the user’s age is 18 or older.

Just use below code and put put inside the script tag

let age = prompt("What is your age?", 18);
let welcome = (age < 18) ?
    () => alert('Hello!') :
    () => alert("Greetings!");

welcome();
