Generate a Random Number Between 1 and 10

The random1To10 function generates a random integer between 1 and 10 using the Math.random and Math.floor methods.

const random1To10 = () => Math.floor(Math.random() * 10) + 1;

console.log(random1To10()); // Example Output: 4
console.log(random1To10()); // Example Output: 7
console.log(random1To10()); // Example Output: 3

How it works:

1. Math.random(): Generates a floating-point number between 0 (inclusive) and 1 (exclusive).

2. Math.random() * 10: Scales the random number to a range of 0 to 10 (exclusive).

3. Math.floor(): Rounds the result down to the nearest integer, creating a range of 0 to 9.

4. + 1: Shifts the range from 0–9 to 1–10.
