Why “Code Is Read More Than Written” Matters in Software Development

-

 Developers say "code is read more than it is written" because maintaining, debugging, and collaborating on software requires far more time spent understanding existing code than writing new lines. This insight drives the importance of clean, readable, and well-documented code.

Why Developers Say “Code Is Read More Than It Is Written”

In the world of software development, one phrase echoes across teams, code reviews, and tech blogs: “Code is read more than it is written.” But what does this really mean, and why is it such a cornerstone of programming wisdom?

Whether you're a seasoned developer or just starting out, understanding this principle can transform the way you write and maintain code. Let’s dive into why this mantra matters — and how embracing it can make you a better coder.

🧠 The Reality of Software Development

Contrary to popular belief, developers don’t spend most of their time writing fresh code. Instead, they:

  • Read existing code to understand functionality
  • Debug issues by tracing through logic
  • Review teammates’ code for quality and consistency
  • Refactor legacy code to improve performance or readability

In fact, studies and anecdotal evidence from industry veterans suggest that up to 70% of a developer’s time is spent reading code. Writing is just the tip of the iceberg.

🔍 Why Readability Matters

Readable code isn’t just a nice-to-have — it’s a necessity. Here's why:

  • Collaboration: Teams need to understand each other’s code quickly. Cryptic logic slows everyone down.
  • Maintenance: Software evolves. Clean code is easier to update and debug.
  • Scalability: As projects grow, so does complexity. Readable code keeps things manageable.
  • Onboarding: New developers ramp up faster when the codebase is intuitive.

🛠️ Best Practices for Writing Readable Code

To ensure your code is easy to read (and therefore easier to maintain), follow these tips:

  • Use meaningful variable and function names (calculateTotal() is better than calc()).
  • Keep functions short and focused — one task per function.
  • Write comments sparingly but effectively — explain “why,” not “what.”
  • Follow consistent formatting and style guides.
  • Avoid clever hacks — clarity beats cleverness.

💬 What Developers Say

As Dima Plotkin, a backend Java developer with 20+ years of experience, puts it:

“Readable code is not a luxury. It’s a necessity. Investing in readability upfront saves countless hours of confusion, debugging, and frustrated Slack messages later on.”

🔄 Code Is a Living Document

Think of code as a living document — one that will be revisited, revised, and reinterpreted many times. Writing readable code is like writing a good book: it should make sense to others, not just the author.

Final Thought
Next time you sit down to write code, remember: someone — maybe even future you — will have to read it. Make it a pleasant experience. Because in the end, code is read far more than it is written.

Electrical grids, traffic lights, highway signs, air-traffic control, and even hospital networks—they're the large-scale operating systems we rely on to make our lives easier and better. And believe it or not, they're all connected to the Internet. These web-connected systems are so diverse in what they do, they fall into a very nondescript category called the "Internet of Things" (IoT). You might have heard of IoT. It's the same term thrown around to describe those cool gadgets that help us track our fitness, drive our cars, share our photos, stream our music, and check our email from almost anywhere. Chances are, no matter what you've done today, you've taken advantage of some device or system connected to the worldwide "web" of the Internet of Things. However, despite IoT's promising future, it has one very serious setback: it's vulnerable to attack. As much as 70 percent of IoT devices contain security flaws, which means that billions...

Difference between HTML and HTTP

Many folks get confused between these two terms which are associated with the Web. Are they really same? First thing first. HTML is a Language while HTTP is a Protocol. Doesn’t make much sense..? it’s okay! We’ll discuss it in more detail. HTML ( H yper t ext  M arkup  L anguage) is a language for marking the normal text so that it gets converted into hypertext. Again, not so clear. Basically, HTML tags (e.g. “<head>”, “<body>” etc.) are used to  tag  or  mark  normal text so that it becomes hypertext and several hypertext pages can be interlinked with each other resulting in the Web. Please note that the HTML tags are used to help render web pages as well in the Browser. On the contrary, HTTP ( H yper t ext  T ransfer  P rotocol) is a protocol for transferring the hypertext pages from Web Server to Web Browser. For exchanging web pages between Server and Browser, an HTTP session is setup using protocol methods (e.g. G...

Having taken over our daily communications almost entirely, the web is constantly evolving and expanding. With this continuous expansion, it provides you with more and more data which you consume daily. However, all the information that appears on the web, every like, subscription, tweet, downloaded video or uploaded vlog, making all of this possible requires a highly sophisticated computational process working behind it, constantly. The smooth functioning of the web has more to it than just the computational procedure. Current web services operate through a solid and intricate network of RAM, containers, database engines as well as machine learning skills. Importance Of Cloud Technology Due to continuous technological growth and advancements, the demand for cloud computing services is increasing, too. It has become essential for individuals and businesses to have a better storage space with increased security and faster service. There is no doubt about the fact that Goog...
