ja Math.random

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

Math.random() javascript

//Returns a number between 1 and 0
  console.log(Math.random());
  
//if you want a random number between two particular numbers, 
//you can use this function
  function getRandomBetween(min, max) {
    return Math.random() * (max - min) + min;
  }
//Returns a random number between 20 and 170
  console.log(getRandomBetween(20,170));
  
//if you want a random integer number from one number to another 
//(including the min and the max numbers), you can use this function
  function getRandomIntBetween(min, max) {
    min = Math.ceil(min);
    max = Math.floor(max);
    return Math.floor(Math.random() * (max - min + 1)) + min;
  }
  
//Returns a random integer number from 0 to 25
  console.log(getRandomIntInclusive(0,25));

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

// using array and random example function getTheBill() { let names = ["bob", "mike", "matt"]; let randomFriend = Math.floor(Math.random() * names.length); let randomFriendBuyng = names[randomFriend]; return randomFriendBuyng + " is buying us lunch today!"; }
