javascript generate random number between 1000 and 9999 code example

Example 1: javascript random number between 1 and 10

// Genereates a number between 0 to 1;
Math.random();

// to gerate a randome rounded number between 1 to 10;
var theRandomNumber = Math.floor(Math.random() * 10) + 1;

Example 2: angular random number between 1 and 10

function randomNumber(min, max) {
  return Math.random() * (max - min) + min;
}

Example 3: generate random number between two numbers javascript

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 4: 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 5: javascript random number 1 or -1

//an equation that returns either 1 or -1
var number = ((Math.floor(Math.random() * 2) - 2) * 2) + 1
