js random

1//To genereate a number between 0-1
2Math.random();
3//To generate a number that is a whole number rounded down
4Math.floor(Math.random())
5/*To generate a number that is a whole number rounded down between
61 and 10 */
7Math.floor(Math.random() * 10) + 1 //the + 1 makes it so its not 0.

1Math.random() 
2// will return a number between 0 and 1, you can then time it up to get larger numbers.
3//When using bigger numbers remember to use Math.floor if you want it to be a integer
4Math.floor(Math.random() * 10) // Will return a integer between 0 and 9
5Math.floor(Math.random() * 11) // Will return a integer between 0 and 10
6
7// You can make functions aswell 
8function randomNum(min, max) {
9	return Math.floor(Math.random() * (max - min)) + min; // You can remove the Math.floor if you don't want it to be an integer
10}

1function getRandomNumberBetween(min,max){
2    return Math.floor(Math.random()*(max-min+1)+min);
3}

5//usage example: getRandomNumberBetween(20,400); 
6

1function randomNumber(min, max) {
2  return Math.floor(Math.random() * (max - min)) + min;
3}

1Math.floor(Math.random() * 10) + 1 // Random number Between 1 and 10
2// First Math.random give us a random number between 0 and 0,99999
3// The we multiply it by 10
4// And we round dow with Math.floor
5// We add 1 so the result will never be 0 
6
7// Another Example:
8h.floor(Math.random() * 20) + 10 // Random number Between 10 and 20

1// using array and random example
2function getTheBill() {
3  let names = ["bob", "mike", "matt"];
4
5  let randomFriend = Math.floor(Math.random() * names.length);

7  let randomFriendBuyng = names[randomFriend];

9  return randomFriendBuyng + " is buying us lunch today!";
