On the other hand, some programmers write very few remarks, forcing developers to guess what they’re reading as well as leading to poor-quality code.

• The primary goal ought to be maintaining equilibrium. Remarks or comments should only be added if they provide potential value. You can write insightful comments by using the following recommendations:
• For complicated functions, leave comments. Functions with intricate logic, such as those with a hundred lines of code, should contain comments. These comments essentially serve as shorthands for describing what the function is intended to carry out, saving other custom software developers a lot of time.
• At the beginning of every file, type a concise remark. This kind of remark ought to be no longer than three lines and must provide an accurate depiction of the purpose and extent of the code you have written. Within 30 seconds of looking at the document, a colleague ought to be able to determine what it’s all about.
• At the beginning of each class, add remarks. This note outlines the function and boundaries of a class throughout a file.

10) Scanning for Vulnerabilities:

One of the most important responsibilities of security professionals in IT and teams that develop software is managing vulnerabilities.
