How to write a professional code?

Hello Readers, 👋🏻, welcome to my new blog. In this blog, I will tell you some coding mistakes that you should avoid for your professional career. So, without further time delay, let’s get started!

For writing effective code, you should avoid some mistakes. These mistakes can make the code less readable, less effective, and less efficient. You should try to avoid these mistakes when you write code. This practice can help you in the interview as well as in your professional coding journey.

So, let’s see these mistakes one by one!

1) Meaningful Variables Names

If you want to write perfect, clear, and readable code, you have to write good and understandable variable names. Writing the good variable names can help you a lot at the time of the interview. And this is the best habit for you as a good coder,

2) Cases in or Programming

There are many cases are available in the programming like Camel Case, Pascal Case, Kebab Case, Snake case & Capitalized Snake Case, etc. If you want that your code looks beautiful, then please stuck on the one case. Don’t write your variable name or function names in different cases. If you use the Camel case, stuck on the Camel case. Don’t change it.

3) Curly Braces

If you write any for, while or other loop, functions, classes, etc, please assign the required curly braces. Curly braces make your code more readable and beautiful.

4) Proper Indentation

Indentation means the gap that you can apply in syntax in simple words. Assign the equal gap when you write a code. Like this,

5) Add Meaningful Comments

Please add the required comments in your code. These comments will help you to understand the code in the future (when you come again in your code). Adding comments is a good habit of a good programmer.

6) Format Your Document

Formatting the document is a good habit for you. It helps you to make your code more beautiful and readable. If you are using the VS Code IDE, Prettier is the best formatting document extension for you!

7) Not backing up your project

This is a mistake that could lose you years of your life. Backing up your code is extremely important, even if you are not working on a team. Do not be intimidated by GitHub! They created a great application called GitHub Desktop. GitHub Desktop makes it extremely easy to sync & save your work without even touching the command line. Best of all, it’s free!

8) Using an overly complicated language

Don’t feel pressured to code in a language that you’re intimidated by just because that’s what many others do, and especially don’t code a custom engine. There are multitudes of easy-to-understand languages that are very beginner-friendly. And, once you know one language, it’s very easy to learn any other language.

9) Not utilizing the debugger

When you run into a code error that you do not know how to solve, don’t make the mistake of just diving into the code and reading. Use the debugger. Most IDEs have them. With the debugger, it makes solving issues a breeze; you can watch your code run line-by-line, so you can see exactly what’s going wrong.

10) Creating functions that are too big

Don’t make functions that take in many inputs, or functions that only accomplish one very specific task. Break up your function into multiple other functions, which are easier to read and maintain.

Example of a function which takes in too many inputs:
