What Is Code Quality? Best Practices to Improve Code Quality

By peeking behind the curtain, you’ve just had a glimpse of the language that tells your computer how this page should appear. The code that you saw was a full mark-up of the page, also known as the document object model . As you can see in some of the other examples here, building a lot of HTML in JavaScript can be pretty daunting and flaky.

It doesn’t matter how beautiful a new app may look, if the underlying code is hard to read then it’s going to be a problem to maintain, update or scale it. In practice, few people update comments when things change. Strive to make your code readable and self-documenting through good naming practices and known programming style.

This is to summarize what the module contains and again give it some context. You should also be wary of deep nesting or storing too many functions within other functions. This can make your code harder to read and may overcomplicate functions. This is usually avoidable by rewriting the code on a single indentation. DRY, or Don’t Repeat Yourself, is a common mantra for coders, and for good reason. DRY coding means that each piece is unique, purpose-built, and representative of a single necessary function in the system.

Leave helpful comments

Additionally, it provides more information to the reader, promotes clarity, and reduces ambiguity. SVP of Professional Services Damian Scalerandi leads every step of IT project delivery with multi-cutural teams to help accomplish client goals. See also the CL Author’s Guide, which gives detailed guidance to developers whose CLs are undergoing review. When you name a method, describe the action it will perform with a verb, such as get, set, transform, or render.

Programmers working as a team have found it better to leave comments behind since coding usually follows cycles, or more than one person may work on a particular module. However, some commenting can decrease the cost of knowledge transfer between developers working on the same module. CERT emphasizes community cooperation and participation. It offers a coding standard that is freely available as a web-based wiki. With CERT, users can comment on specific guidelines – comments taken into account when the standards are reviewed and updated.

Simple Steps To Solve Any Code Algorithm

Tl;dr – There may be plenty of cases where you’ll never need more than a few comments supporting great, readable code and I applaud those who fall into that category. I’m mostly talking about the other 97% that don’t. Links to standards and other documentation can help readers understand the problem your code is solving.

The fact is that there is no such thing as perfectly readable code. What’s readable to one person is a complete ball of mud to others. To force someone to read code just as a form of documentation is an irresponsible idea that is inefficient and assumes that only developers of a certain level should be looking at your code.

Do you remember the IDEs we talked about a few minutes ago? Many of those tools like Eclipse IDE and Visual Studio include automated refactoring, https://globalcloudteam.com/ too, allowing you to speed up the process. Of course, automated refactoring isn’t essential as you can also opt for the manual method.

React Best Practices – Tips for Writing Better React Code in 2022

As those very same developers could tell you, software development has a series of coding standards and practices that most of them are undoubtedly familiar with. They are included in software development courses, shared in development teams, or even learned in the wild. The main problem is that they aren’t standardized or formally formulated – they are tricks of the trade that developers are encouraged to follow in order to write good code.

• The best thing is when the code is self-explaining, but it’s always recommended to add comments to the code to explain its role and functions.
• This tool offers thousands of static code analysis rules covering 29 programming languages.
• I’ve written whole code bases without a single comment, and they are perfectly readable.
• It should include some consideration of any user interfaces as well, without going into excessive detail.
• Article Tools to Track and Manage Technical Debt If you are looking for a tool to start managing technical debt this article will help you make the right decision.

Otherwise, the application will not run on a host that has a different design than anticipated. A careful programmer can parametrize such variables and configure them for the hosting environment outside of the application proper . Compare the mantra of a “single point of definition”. A high-quality code, as previously stated, has high readability and is simple to change.

The Complete Engineer’s Guide to Code Refactoring

A style guide is a compilation of design principles and conventions. Using a style guide guarantees that every developer’s code looks identical, making it easy to review and work with. For example, we might add a comment explaining the code’s business application or the rationale for choosing a particular algorithm. You can use these coding standards best practices as a starting point. The next step is to evaluate coding standards based on your needs.

However, if an issue occurs, the code build does not run, and the CI system prohibits it from progressing to the next phase. The team then receives a report and can promptly correct the problem. While most developers underestimate code architecture when faced with tight deadlines.

Maintainability:

One of the goals of coding standards is to educate programmers. And supporting material to a coding standard can provide that education. So, CERT puts the emphasis on community cooperation. The result is a coding standard in the form of an open, freely available web-based wiki.

The only snag is to tell them which IDs are needed and if there are certain HTML constructs that need to be in the order you defined. You can do that with inline HTML comments (and then strip the comments out when you load the template. Check the source of the Easy YouTube template as an example. This is wasted time and effort — we should build code based on agreed standards as outlined in this course of articles, not for one browser.

Software architecture is concerned with deciding what has to be done and which program component is going to do it . This is particularly important when a software system contains more than one program since it effectively defines the interface between these various programs. It should include some consideration of any user interfaces as well, without going into excessive detail. The waterfall model is a sequential pursuing better code practices development approach; in particular, it assumes that the requirements can be completely defined at the start of a project. However, McConnell quotes three studies that indicate that, on average, requirements change by around 25% during a project. The other methodologies mentioned above all attempt to reduce the impact of such requirement changes, often by some form of step-wise, incremental, or iterative approach.

In his spare time he podcasts and writes books about making fact-based decisions in business and politics. Consistently named variables are easier to search and implement than randomly named ones. Having a set convention can make longer sections of code more readable for both people and machines. If you have any other queries or anything to add about best coding practices, then do let us know in the comments below. DRY (Don’t Repeat Yourself) matters much less in tests than it does in production code. Readability of an individual test file is more important than maintainability .

It offers a sleek interface, includes drag-and-drop functionality, and the possibility to do static analysis. The same company also offers other IDEs supporting other languages. Remove sensitive data before publishing your project. Did you just publish your project on GitHub and suddenly realize that you forgot to remove some credentials and tokens from it?

Code reviews are the manual way of checking if code changes are following standards and are good to be submitted. Almost all version control systems support code review processes and help in enforcing rules across the project. The very first thing for ensuring the code quality is following standard, well-documented coding guidelines.

Testing is an integral part of software development that needs to be planned. In particular, it consumes 5 times more screen vertical space , and 97 characters versus 52 . The first has an explicit if/then else, with an explicit return value obviously connected with each; even a novice programmer should have no difficulty understanding it. The 2nd merely discards the braces, cutting the “vertical” size in half with little change in conceptual complexity.

And it could include code examples of compliant and noncompliant behavior — and exceptions to the rule. The coding standard must be recognized and accepted by the industry for which it is being used. One of the biggest problems with repetitive code is that it can lead to increased technical debt. Additionally, it can make your code more vulnerable to security threats and risks.

Store it both physically on your computer and in cloud storage software if possible so that you can access it from anywhere without serious issue. In a simplistic thought, CODER is the obtaining process of excellent writing skills. Try out every possible solution to the current problem until you fix it. In the debugging process, having strong willpower is the most important. Back up your current working progression every time after a modification. You can choose a version control mechanism like TFS, SVN, etc.

The longer you leave the debt around, the higher the interest it accumulates. A great book on refactoring and testing is Working Effectively with Legacy Code, by Michael Feathers. First, the code’s author will know why they should make a particular change, which will help them tackle similar problems in the future. Second, since you already justified your comments, they won’t need to follow up with you about the reasoning behind your comment, saving both of you time.

Use the same labeling conventions on variables and functions, indent and organize lines the same way and have consistent nesting procedures. Consistency is another benefit to keeping a style guide. Naming precisely in code will help a new member cope faster with a different programming language. Because every programming language uses a specific style for naming conventions. And, naming conventions weirdly can inform an experienced developer to halt the process and suggest a fix.
