Make it simple for everyone who works with your code to comprehend the names of your variables, functions, and other code structures. Avoid using either too short or too lengthy names and ensure that they accurately indicate their intended usage.
In programming, commenting is a widespread issue. Sometimes some argue that comments are unnecessary, code without them becomes difficult to comprehend, mainly when working on collaborative or legacy projects. On the other hand, excessively lengthy and verbose remarks are superfluous since they need more time to read and comprehend.
As a general guideline, comment on your code, mainly functions, classes, objects, and interfaces, but provide just the most critical information. Utilize tags to make your comments succinct and straightforward to read.
As stated in the first SOLID design principle (single responsibility), each function, interface, class, and code structure should have a purpose. One option to adhere to this idea is to create helper functions for frequent activities.
First, you must avoid developing superfluous classes to create a well-structured program. Moreover, classes may be irrelevant for a variety of reasons, including the following:
- Classes that have many purposes (or everything)
- Classes that contain just data (properties) but no methods — attempt to relocate the data to another class.
- Classes that include just activity (methods) but no data (properties) are preferable to build a function in this scenario.
You must always define a class before calling it; else, an uncaught reference error will occur. Using the Product class as an example:
