JavaScript Random
In JavaScript, the Math.random() method returns a random number between 0 (inclusive) and 1 (exclusive). This means that it can return a value that is equal to or greater than 0, but always less than 1.
To generate a random number within a specific range, you can use the Math.random() method in combination with other math functions, such as Math.floor() or Math.ceil(). For example, to generate a random integer between 1 and 10 (inclusive), you can use the following code:
const randomNum = Math.floor(Math.random() * 10) + 1;
In this code, Math.random() generates a random number between 0 and 1, which is then multiplied by 10 to get a random number between 0 (inclusive) and 10 (exclusive). The Math.floor() function rounds down this number to the nearest integer, which gives us a random integer between 0 and 9. Finally, we add 1 to this value to get a random integer between 1 and 10.
If you want to generate a random number within a specific range that includes decimals, you can use the following code:
const randomNum = Math.random() * (max - min) + min;
In this code, max and min represent the maximum and minimum values of the range you want to generate a random number within. The expression Math.random() * (max – min) generates a random number between 0 (inclusive) and max – min (exclusive). Adding min to this value gives us a random number between min (inclusive) and max (exclusive).
