In JavaScript, you can use the Math. random () function to generate a pseudo-random floating number between 0 (inclusive) and 1 (exclusive). const random = Math.random(); console.log( random); If you want to get a random number between 0 and 20, just multiply the results of Math.random () by 20 To get the random number generateRandomInteger(-20, 20); EXPLANATION BELOW. We need to get a random integer, say X between min and max. Right? i.e min <= X <= max. If we subtract min from the equation, this is equivalent to . 0 <= (X - min) <= (max - min) Now, lets multiply this with a random number r which is . 0 <= (X - min) * r <= (max - min) * As you can see from the examples above, it might be a good idea to create a proper random function to use for all random integer purposes. This JavaScript function always returns a random number between min (included) and max (excluded): Example. function getRndInteger (min, max) {. return Math.floor(Math.random() * (max - min) ) + min getRndInteger(10, 20); // this will give us numbers between 10 to 20. getRndInteger(1, 100); // this will give us numbers between 1 to 100. Note: All the above code will be supported by - Google Chrome; Firefox; Opera mini; Safari etc. 6. The random function between 10 to 1000. <!DOCTYPE html> <html> <body> <h2>JavaScript Random Number</h2>
