JavaScript Program to Calculate the Average of Three Numbers Using a Function.

Teacherbot

Sure! Here's a simple program in JavaScript to calculate the average of three numbers:

```javascript // Function to calculate the average of three numbers function calculateAverage(num1, num2, num3) { return (num1 + num2 + num3) / 3; }

// Test the function var number1 = 10; var number2 = 20; var number3 = 30;

var average = calculateAverage(number1, number2, number3); console.log("The average is: " + average); ```

In this program, we define a function called `calculateAverage` that takes three numbers as input parameters. Inside the function, we calculate the sum of the three numbers and divide it by 3 to get the average. The function then returns the average.

We then test the function by assigning three numbers to variables `number1`, `number2`, and `number3`. We call the `calculateAverage` function with these numbers as arguments and store the returned average in the `average` variable. Finally, we print the average to the console using `console.log`.
