(JavaScript programming Example for Beginners)
JavaScript Program to Guess a Random Number
In this example, you will learn to write a JavaScript program where the user has to guess a number generated by a program.
Example: Program to Guess a Number
// program where the user has to guess a number generated by a program
function guessNumber() {
// generating a random integer from 1 to 10
let random = Math.floor(Math.random() * 10) + 1;
// take input from the user
let number = parseInt(prompt('Guess a number from 1 to 10: '));
// take the input until the guess is correct
while(number !== random) {
number = parseInt(prompt('Guess a number from 1 to 10: '));
}
// check if the guess is correct
if(number == random) {
console.log('You guessed the correct number.');
}
}
// call the function
guessNumber();
Output
Guess a number from 1 to 10: 1 Guess a number from 1 to 10: 8 Guess a number from 1 to 10: 5 Guess a number from 1 to 10: 4 You guessed the correct number.
Note: You will get different output values each time you run the program because each time a different number is generated.
In the above program, the guessNumber()
function is created where a random number from 1 to 10 is generated using Math.random()
function.
