Separation of Concerns (SoC): Separation of Concerns Principle partition a complicated application into different sections or domains. This principle is so important to understand, that I won't write it twice! If your code is simple then other developers won’t face any problem understanding the code logic and they can easily proceed further with your code. 7 Common Programming Principles. Web development encompasses several actions or practices and some of them include web design, content creation, programming, network security tasks as well as client side or server side scripting, etc. If we give you a half story to continue it, how would you do that? I ran it on my machine and it worked perfectly, so let’s just ship it.The goal of testing software is not to find bugs or to make software better. Separation of Concerns (SoC): Separation of Concerns Principle partition a complicated application into different sections or domains. Each section or domain addresses a separate concern or has a specific job. The purpose of software engineering is to reduce complexity, not to create it.-Pamela Zave. They don’t think it’s necessary.At a surface level, it can seem a bit extraneous.Do we really need to test that code? No matter how good a coder you are, in programming, your job is not just writing code that works and give you the desired output but also writing a code that is maintainable, extensible and easy to understand so later the one who continue or maintains your project can understand it and he/she doesn’t have to go through a horror story which gives him/her a nightmare.

SOLID principles focus on enhancing the understandability of software design, boosting scalability, and maintenance. “Keep It Simple, Stupid (KISS)“ states that most systems work best if they are kept simple rather than making it complex, so when you are writing code your solution should not be complicated that takes a lot of time and effort to understand. So it’s better to optimize the algorithm at the right time to get the right benefit of it.

Head Start programs are effective when their systems and services support the cultural diversity of enrolled families. It states that a piece of code should be implemented in just one place in the source code. -Pamela Zave. Each section is independent of each other and that’s why each section can be tackled independently also it becomes easier to maintain, update and reuse the code.For example business logic (the content of the webpage) in an application is a different concern and user interface is a different concern in a web application program. Doing this is completely wrong and you will eventually end up in writing bloated code also your project becomes complicated and difficult to maintain. They add all the unnecessary class and functionality which they might never use in the future.
