Exercise prompt

Trace a while Loop

A while loop repeats as long as its condition is true. Code inside the loop must eventually change the value used by that condition.

Example

let lives = 2;
while (lives > 0) {
  console.log("Lives:", lives);
  lives -= 1;
}

Your task

Read the battery loop and predict the value of battery after it finishes. Replace the empty prediction while keeping the loop and Actual: line unchanged.

Hint

Check the condition again after each update.
