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.
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
Declare a function named
calculateVolume that takes three parameters:
calculateVolume function, call the
calculateArea function with
height as arguments.
Multiply the result of the
calculateArea function by
length and return the result.
calculateVolume function with arguments
30, and log the result to the console.
