js random int between two numbers code example

Example 1: random int between two numbers javascript

// Between any two numbers
Math.floor(Math.random() * (max - min + 1)) + min;

// Between 0 and max
Math.floor(Math.random() * (max + 1));

// Between 1 and max
Math.floor(Math.random() * max) + 1;

Example 2: javascript random no between 2 numbers

function randomIntFromInterval(min, max) { // min and max included 
  return Math.floor(Math.random() * (max - min + 1) + min);
}

Example 3: typescript random number

/**
* Gets random int
* @param min 
* @param max 
* @returns random int - min & max inclusive
*/
getRandomInt(min, max) : number{
	min = Math.ceil(min);
	max = Math.floor(max);
	return Math.floor(Math.random() * (max - min + 1)) + min; 
}

Example 4: randint js

/* If 1 argument is given, minimum will be set to 0 and maximum to this argument
 * If 2 arguments were given, the fist would be the minimum and the second the maximum
 * The function will return an integer in [min, max[
 */
const Math.randint => (min,max) {
  [min,max] = (max===undefined)?[0,min]:(min>max)[max,min]:[min,max];
  return Math.floor(Math.random*(max-min)+min);
}
