The Problem: Redundant If Statements

Original Function Highlights

[[See Video to Reveal this Text or Code Snippet]]

From the code above, notice how the function checks if a file uploader exists. In both branches of the if statement, the logic to redirect the user after a successful API call is duplicated. This introduces redundancy, making the function harder to read and maintain.

The Solution: Refactoring for Clarity

To enhance the maintainability and clarity of our code, we can refactor the editDetails function by abstracting the API call into a separate function. This way, we can leverage the same logic for both cases, ultimately cleaning up our code significantly.

Step 1: Create a Separate Function

First, we create a new function called uploadProfile. This function will handle the sending of profile data and the navigation upon success:

Step 2: Updating the Original Function

Now, we can update our original function to utilize this new helper method. We will call uploadProfile from two different locations based on whether the user has provided a file or not:

Benefits of the Refactored Code

By refactoring the code in this manner, several advantages arise:

Decreased Redundancy: The redirect logic is unified and written only once, reducing the potential for errors during future updates.

Increased Readability: The purpose of each function is more defined, making the code easier to understand for future developers (or yourself!).

Maintainability: Future changes related to how profile data is processed only need to occur in one location, simplifying the maintenance process.
