From Concept to Code

The "average" (or mean) is a single number that summarizes a group of numbers. It gives you a sense of the typical value in the set.

An algorithm is a blueprint for solving a problem. It’s the step-by-step logic we create before writing a single line of code.

Let's translate our algorithm into JavaScript, learning the core building blocks of programming.

Your Turn to Code!

Fill in the missing line in the function below to complete the average calculation.

function calculateAverage(numbers) {
  let sum = 0;

  for (let i = 0; i < numbers.length; i++) {
    sum += numbers[i];
  }

  // YOUR CODE HERE: Calculate the average
  

  return average;
}
