What is reusable code?
In our book, a reusable code is the smallest unit of code performing a function or an action. It can be a single line of code.
It's a concept, a code snippet, a reusable script, an example, etc. As the name suggests, it's usable across several projects and situations.
A reusable code expresses a basic idea, while the software is the specific application of the concept (and many others). A reusable code represents the programming side of the abstraction. Integrating reusable code into larger programming modules or software requires adjustments.
Recommendation for code reuse
A sound reusable snippet has the following attributes:
- Representing a single idea, function, or actions
- Separate the abstraction from the specific implementation
- Testable
- Easily reusable in various project
- Enough comments & explanations
The less time you spend understanding the code, the easier it is to reuse, adjust, and implement, and the better your reusable snippet is.
Remember, you may forget the solution to a problem, but you will always remember you had it and solved it somehow. Hence, we recommend keeping track of your accumulated knowledge and storing it in a dedicated place.It will be helpful over time: you will know where to search and avoid the research time.
