While Loops

You can think of a while loop as a board game that goes on an indefinite amount of times until a winner is found, We have a clear vision of what we need to do to win the game but we're not sure of how long it will take since its dependant on outside factors like chance, number of people playing the game.

Check out this example:

let user1 = 0;
let user2 = 0;
let winScore = 3;
while(user1 < winScore && user2 < winScore) {
    let dice1 = Math.random()
    let dice2 = Math.random()
    if (dice1 > dice2) {
      user1 += 1;
    } else if (dice2 > dice1)  {
      user2 += 1;
    }
    if (user1 === 3) {
      console.log('user1 is winner');
    } else if (user2 === 3) {
      console.log('user2 is winner');
    }
};

The syntax of a while loop is pretty straightforward, While a condition is true or false we want to execute a piece of code. The condition is always placed inside parentheses right after the while keyword, and as long as that condition is met we're running a piece of code that in most cases, to not create infinite loops we want that piece of code inside of the loop to modify the variables being evaluated in the condition. (the block of code after the while loop statement goes in between a pair of curly braces);
