what are coding standards?
Implementations of rules, techniques, and best practices to write cleaner, safer, smaller, reliable, scalable and efficient code with minimal errors. It’s a uniform way to write a perfect code with high functionality.
Coding standards ensure that program is:
# Safe : It can be used without loss.
# Secure: It cannot be hacked.
# Reliable: It will perform same, every time.
# Testable: It can be tested at every level of development with different combinations of functionalities.
# Maintainable: It can be maintained, while scaling the scope of utilities.
# Portable: It works properly in any environment.
Advantages of implementing Coding Standards
# promoting the writing of reusable codes.
# encourages uniformity in writing of codes by different developers.
# makes it easier to detect errors in the code.
# boosts coding efficiency and generates faster results with minimum errors.
# improves code execution time and accuracy of result.
Best Practices to follow coding standards
Make sure your code is readable
As a developer focus on that whatever you write code should be readable. Code that can be understood can be integrated more easily, providing scope of greater efficiency in the project as a whole.
Comment and Document
Comments and documents pay important role in coding standards, it will provide accurate information about the actions that the code performs, including any dependencies.
Keep you code DRY (Don’t Repeat Yourself)
Remember the DRY principle when following the coding standards, the Principle states that “Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.” In short “Duplication is dangerous.
Try to keep code length short
Try to write codes smaller than 80 characters in a line. If you find your code is longer than fifty lines, split it up into shorter, when you divide these long sections of code into blocks, consider adding a comment at the beginning of each block.
As much as possible, avoid hard-coding, security pitfalls should always be avoided, learn about the possible risks inherent in your language and in hard-coding, and avoid them as much as possible.
