In this JavaScript lesson from Codecademy’s JavaScript course we look at What are Helper Functions, How to Use a Helper Function in JavaScript, Programming and we first learn that they are used to help another function. When a function is called within another function, this is also called oftenly helper functions. Helper functions help us seperate logic into simpler steps, each function doing one task, then using a functions return value in another function could help sanitize our code from potential bugs or difficulty in finding bugs from code complexity. Seperating logic helps make our code easier to read, and finding bugs is much easier when using helper functions! Learn them and continue on your journey of master JavaScript, and all of programming logic.

If you’re looking to improve your JavaScript programming skills, you’ll want to know about helper functions. In this lesson from Codecademy’s JavaScript course, you’ll learn what helper functions are and how to use them in your code.

A helper function is simply a function that is used within another function. It is a tool that can help simplify the logic of a program by breaking down complex tasks into smaller, more manageable steps. By using helper functions, you can make your code more organized, easier to read, and less prone to bugs.

One of the key benefits of using helper functions is that they allow you to separate your code into smaller, more focused parts. This can help you avoid the pitfalls of writing overly complex code, which can be difficult to read, understand, and debug. By breaking down complex tasks into smaller, more manageable steps, you can make your code more modular and easier to maintain.

When using helper functions, it’s important to understand that each function should have one specific task that it is responsible for. This helps to keep your code organized and makes it easier to read and understand. It’s also important to remember that helper functions can be reused multiple times throughout your code, which can help you avoid duplicating code and reduce the amount of time it takes to write your program.

To use a helper function in JavaScript, you simply define the function and then call it within another function. For example, if you have a function that calculates the area of a rectangle, you might create a helper function that calculates the perimeter of the same rectangle. You can then call the perimeter function within the area function to help calculate the total area of the rectangle.

When using helper functions, it’s important to keep in mind that each function should have a clear and specific purpose. This will help you avoid confusion and ensure that your code is easy to read and understand. Additionally, it’s important to make sure that your helper functions are well-documented, with clear comments explaining what the function does, what inputs it takes, and what outputs it produces.

In summary, helper functions are a valuable tool in JavaScript programming that can help you write more organized, efficient, and bug-free code. By breaking down complex tasks into smaller, more manageable steps, you can make your code more modular and easier to maintain. If you’re new to JavaScript programming, take the time to learn about helper functions and how to use them effectively in your code. Codecademy’s JavaScript course provides a great introduction to helper functions and other important programming concepts.
