While

Like many other languages, JavaScript has a while loop. It keeps running as long as the condition is true.

const jane = {
  name: "Jane",
  mom: {
    name: "Alice",
    mom: {
      name: "Lilly",
      mom: {
        name: "Granny",
      },
    },
  },
};

let currentPerson = jane;
while (currentPerson) {
  console.log(currentPerson.name);
  currentPerson = currentPerson.mom;
}
console.log("No more ancestors!");
// Jane
// Alice
// Lilly
// Granny
// No more ancestors!

Assignment

We charge exponentially more money for each consecutive text sent... because we're a greedy SAAS. Don't judge.

The getMaxMessagesToSend calculates how many messages can be sent by a user based on a multiplier and the total amount they have to spend. The first message costs a penny, and each message after that costs the same as the previous message multiplied by the costMultiplier.

There is a bug in the code! The while loop responsible for accumulating the total cost should keep running until the balance runs out, fix it.
