Generate random number between 1 and 10 in javascript

In this post, we will see how to generate random number between 1 to 10 in javascript. How to generate random number between 1 and 10 in javascript We can simply Math.random() method to generate random number between 1 and 10 in javascript. `Math.random()` returns a random number between 0(inclusive), and 1(exclusive). That means `Math.random()` returns always number lower than 1. We can use `Math.random()` with `Math.floor()` to generate random integer. Here is generic formula to generate random number in the range. Math.floor(Math.random() * (maximum - minimum + 1)) + minimum In our case, minimum = 1 maximum = 10 so it will be Math.floor(Math.random() * (10 - 1 + 1)) + 1 Math.floor(Math.random() * 10) + 1 So here is the program to generate random number between 1 and 10 in javascript. var randNum = Math.floor(Math.random() * 10) + 1; console.log(randNum) When you run above program, you will get below output: 3 You can obviously get differnt outout as we are generating random number here. Generate 10 random integers in range of 1 to 10 console.log("Generating 10 random integers in range of 1 to 10") for (let i = 0; i < 10; i++) { var randNum = Math.floor(Math.random() * 10) + 1; console.log(randNum) } Generate 10 random integers in range of 1 to 10 7 5 1 10 5 9 7 7 6 2 Generate random number in a range in javascript Here is generic formula to generate random number in a range. function generateRandomInteger(min, max) { return Math.floor(Math.random() * (max - min + 1)) + min; } // Generate random number between 1 to 10 console.log(generateRandomInteger(1,10)) // Generate random number between 11 to 20 console.log(generateRandomInteger(11,20)) // Generate random number between 21 to 30 console.log(generateRandomInteger(21,30)) 4 17 28 In case, if you don't want to include maximum while generating random numbers, you can use below function. function generateRandomInteger(min, max) { return Math.floor(Math.random() * (max - min)) + min; } That's all about how to generate random number between 1 and 10 in javascript

In this post, we will see how to generate random number between 1 to 10 in javascript.

How to generate random number between 1 and 10 in javascript

We can simply Math.random() method to generate random number between 1 and 10 in javascript.

Math.random() returns a random number between 0(inclusive), and 1(exclusive). That means Math.random() returns always number lower than 1.

We can use Math.random() with Math.floor() to generate random integer.

Here is generic formula to generate random number in the range.

Math.floor(Math.random() * (maximum – minimum + 1)) + minimum
In our case,
minimum = 1
maximum = 10

so it will be
Math.floor(Math.random() * (10 – 1 + 1)) + 1
Math.floor(Math.random() * 10) + 1

So here is the program to generate random number between 1 and 10 in javascript.

When you run above program, you will get below output:

You can get different outputs as we are generating random numbers here.
