  • 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
