Answers for "random number within a range javascript"

random in a range js

const rnd = (min,max) => { return Math.floor(Math.random() * (max - min + 1) + min) };

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; 
}

javascript random number in range

function getRandomIntInclusive(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min + 1)) + min; //The maximum is inclusive and the minimum is inclusive 
}

random number in range js

var min = 10, max = 25;
//inclusive random (can output 25)
var random = Math.round(Math.random() * (max - min) + min);
//exclusive random (max number that can be output is 24, in this case)
var random = Math.floor(Math.random() * (max - min) + min);
//floor takes the number beneath the generated random and round takes
//which ever is the closest to the decimal

Generate a number range js

const range = (options) => {
  const { from = 0, step = 1, to } = options;

  if (!to) {
    throw Error('"to" must be specified');
  }

  if (to <= from) {
    throw Error(`"to (${to})" is lesser than or equal to "from (${from})"`);
  }

  return Array.from(
    { length: Math.ceil((to - from) / step) },
    (_, i) => i * step + from
  );
};

// Usage
const r1 = range({ to: 10 });
// [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

const r2 = range({ from: 10, to: 20 });
// [10, 11, 12, 13, 14, 15, 16, 17, 18, 19]

const r3 = range({ from: 10, to: 20, step: 3 });
// [10, 13, 16, 19]
