Helper Functions
When writing complex code, it is common to encounter scenarios where a single function cannot handle all the necessary tasks. This is where helper functions come in handy. By creating separate helper functions for specific tasks, you can avoid repetition, improve code readability, and modularize your code.
Creating and Using Helper Functions
To create a helper function, you can follow the same steps as creating any other function. The only difference is that a helper function is not intended to be used on its own; instead, it is meant to be called within another function.
Here's an example of a helper function that calculates the average of two numbers:
In the code above, the function calculateAverage
is a helper function that takes two numbers as parameters and returns their average. Later in the calculateSumAndAverage
function, we call the calculateAverage
function to calculate the average of num1
and num2
.
Instructions
Declare a function named calculateVolume
that takes three parameters: length
, width
, and height
.
Inside the calculateVolume
function, call the calculateArea
function with width
and height
as arguments.
Multiply the result of the calculateArea
function by length
and return the result.
Call the calculateVolume
function with arguments 10
, 20
, and 30
, and log the result to the console.
