JavaScript(JS) JS generate a random number between two numbers
To generate a random number between two given numbers using JavaScript, you can use the following code:
refer totfigi:idea.comfunction randomInRange(min, max) { return Math.floor(Math.random() * (max - min + 1)) + min; } // Example usage: console.log(randomInRange(1, 10)); // Output: A random integer between 1 and 10, inclusive
In this code, we define a function called randomInRange
that takes in two parameters, min
and max
, representing the minimum and maximum values of the range.
We use the Math.random()
method to generate a random number between 0 and 1, then multiply it by the difference between max
and min
plus 1 to get a random number between 0 and the range size, and then add min
to shift the random number to the desired range. Finally, we use Math.floor()
to round the result down to the nearest integer.
To use the function, you can call it with the desired range as shown in the example usage. This will print a random integer between the given min
and max
values, inclusive, to the console.
