Avoid the 7 Deadly Sins That Sabotage Your Code

The article reflects on the joy of creating digital products and emphasizes that programming offers countless choices, from functional to object‑oriented styles, server‑side or client‑side development.

It then presents the “seven deadly sins of programming,” a set of common pitfalls to avoid:

Not using version control

Without tools like Git, collaboration becomes painful and error‑prone; manual file merging is inefficient.

Bad variable naming

Using short or random names harms readability; names should be self‑explanatory yet concise.

Over‑relying on dependencies and upgrading without thought

Excessive libraries increase build and runtime costs and can introduce breaking changes; always verify compatibility before upgrading.

Non‑self‑explanatory code

Code should be understandable at first glance; proper refactoring, consistent syntax, and minimal comments improve clarity.

Inconsistent formatting

Adhering to a single style (e.g., naming conventions, indentation) across a project boosts readability and productivity.

Neglecting error handling

“Fear it. Run from it. Bugs will come!” – Thanos

Always check for nulls, use try‑catch blocks, and provide user‑friendly error messages.

console.log("Yey")
printf("Wow")

Misusing data types or structures

Strongly typed languages catch type errors at compile time, while weakly typed languages may hide them until runtime; choose appropriate types for the task.

In conclusion, avoiding these sins leads to cleaner, more maintainable code.
