Sometimes, we want to generate a 4 digit random number with JavaScript.
In this article, we’ll look at how to generate a 4 digit random number with JavaScript.
Generate a 4 Digit Random Number with JavaScript
To generate a 4 digit random number with JavaScript, we can use the Math.random method.
For instance, we can write:
const val = Math.floor(1000 + Math.random() * 9000);
console.log(val);
We call the Math.random method to generate a random number between 0 and 1.
Then we multiply that by 9000 to get a number between 0 and 9000.
Then to get a number between 0 and 10000, we add 1000 to the returned number.
Finally, we call Math.floor on the generated number to round it down to a number between 1000 and 9999.
Conclusion
To generate a 4 digit random number with JavaScript, we can use the Math.random method.
