Following Javascript best practices.

[kessie2862]

• The code appears to be following the DRY principle by using functions and variables to avoid repetition. It also uses variables to store elements and data that are reused throughout the code.

• The code also appears to be following the KISS principle by using simple and straightforward code structures and avoiding unnecessary complexity.

• The code also appears to be following the YAGNI principle by only implementing features and functionality that are necessary for the task at hand. It only includes features that are required for creating and managing a task list, such as adding tasks, editing tasks, marking tasks as completed, and deleting tasks.

• The code could benefit from more comments to explain the purpose of the code, functions, and variables, making it easier for other developers to understand and maintain the code.

• The code does not handle errors or unexpected situations, such as when a user enters an empty task description. It's best practice to include error handling to prevent unexpected errors and improve user experience.
