random number generation in javascript code example

Example 1: how to generate a random number in javascript

//To genereate a number between 0-1
Math.random();
//To generate a number that is a whole number rounded down
Math.floor(Math.random())
/*To generate a number that is a whole number rounded down between
1 and 10 */
Math.floor(Math.random() * 10) + 1 //the + 1 makes it so its not 0.

Example 2: generate random number javascript

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

Example 3: javascript generate random number

Math.random();

Example 4: how to generate a random number in javascript

// min value of the random number
var min = 5;

// max value of the random number
var max = 25;

// generate the random number
var rdm = (Math.random() * (max - min)) + min

// generate the random number without "."
var rdm = Math.round((Math.random() * (max - min)) + min)

Example 5: generate random integer javascript

/**
 * Returns a random number between min (inclusive) and max (exclusive)
 */
function getRandomArbitrary(min, max) {
    return Math.random() * (max - min) + min;
}

/**
 * Returns a random integer between min (inclusive) and max (inclusive).
 * The value is no lower than min (or the next integer greater than min
 * if min isn't an integer) and no greater than max (or the next integer
 * lower than max if max isn't an integer).
 * Using Math.round() will give you a non-uniform distribution!
 */
function getRandomInt(min, max) {
    min = Math.ceil(min);
    max = Math.floor(max);
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

Example 6: generate random number javascript

// generates random float between 0-1
Math.random()
