Why should design patterns be implemented in javascript?

I recently delved into the world of Design patterns and stumbled upon the Module Design pattern in JavaScript. This pattern offers object-oriented features like private and public variables in JavaScript. However, I found myself questioning the need to designate these variables as private or public. After all, even a novice developer can easily view the Javascript code in applications using browser tools like inspect elements and access those variables via breakpoints. What then is the significance of making them private or public?

Answer №1

One of the main focuses of the Module pattern is to manage variable scope in a way that avoids cluttering up the global namespace.

Answer №2

Implementing both private and public design patterns can help minimize potential errors in your code. As you gain experience in coding, you will come to appreciate the value it brings.

Additionally, many developers opt to use private functions for sensitive information that they prefer not to expose in the global scope, such as email addresses.
