How to Optimize Your Code with Better Formatting

ankitchugh006@gmail.com October 4, 2024

As developers, we often focus on functionality and performance, but code formatting is equally important in ensuring maintainability, readability, and overall project success. Clean, well-formatted code is easier to understand, debug, and extend, making it a vital skill for any developer, especially when working in teams.

In this article, we’ll explore why code formatting matters, best practices for different languages, and how you can optimize your code using tools like DevToolsHub.online.

Why Code Formatting Matters

Well-formatted code is not just about aesthetics—it directly impacts the following:

  • Readability: Clear, organized code is easier to read and understand, making it less time-consuming to debug and maintain.
  • Collaboration: Consistent formatting ensures that everyone in a team is on the same page, reducing errors and misunderstandings.
  • Error Reduction: Misplaced brackets, inconsistent indentation, or poor structure can lead to errors that are hard to track down.
  • Code Quality: Clean formatting makes it easier to spot bugs, enforce best practices, and adhere to coding standards.
  • Maintainability: As projects grow, maintaining code becomes a breeze when it’s organized and easy to follow.

Best Practices for Code Formatting

Here are some best practices to follow when formatting your code:

1. Consistent Indentation

  • Whether you prefer tabs or spaces, choose one and stick to it throughout your codebase. Typically, 2 or 4 spaces are used for indentation.
  • HTML/CSS/JS Tip: Keep your opening and closing tags properly aligned for easy navigation.

2. Proper Use of Line Breaks

  • Use line breaks to separate logical sections of your code. This not only improves readability but also helps break up dense blocks of code.
  • For JavaScript, use line breaks after each function, condition, or loop.

3. Group Related Code Together

  • Group similar functions, styles, or elements in a way that makes sense. For example, in CSS, keep all typography-related styles together.
  • Use comments to separate different sections.

4. Minimize Nesting

  • Avoid excessive nesting of functions or elements in your code, as it can make it hard to follow. Flatten your code as much as possible.

5. Comment Your Code

  • While comments are not part of code formatting, they complement well-structured code by explaining complex sections. However, avoid over-commenting or stating the obvious.

Badly Formatted Code Examples

To understand how poor formatting can affect code readability and maintainability, let’s look at some badly formatted examples across different languages.

Badly Formatted HTML Example

<html><head><title>My Page</title></head><body><h1>Welcome to My Page</h1><p>This is an example.</p><div><ul><li>Item 1</li><li>Item 2</li><li>Item 3</li></ul></div></body></html>
Problems:
  • No line breaks between tags.
  • Inconsistent nesting makes it difficult to follow the structure.
  • All code is crammed into one line.

Badly Formatted CSS Example

body{font-size:16px;color:#333;}h1 {font-size:32px;color:red;}p{line-height:1.5;margin:10px;padding:5px;}ul{list-style-type:none;}li{margin-bottom:10px;}
Problems:
  • Everything is written in one line, which makes it unreadable.
  • No consistent use of spacing or line breaks.
  • Makes future edits time-consuming and error-prone.

Badly Formatted JavaScript Example

codefunction add(a,b){var sum=a+b;return sum;}if(sum>10){console.log('Greater than 10')}else{console.log('10 or less');}
Problems:
  • No line breaks or indentation for readability.
  • Missing spacing around the operators (+, >).
  • The if statement block is not indented properly.

Badly Formatted JSON Example

{"name":"John","age":30,"city":"New York","skills":["JavaScript","HTML","CSS"],"education":{"degree":"BSc","university":"XYZ University"}}
Problems:
  • Entire JSON object is on one line.
  • Hard to read and modify, especially in larger datasets.
  • Makes debugging more difficult.

Code Formatting by Language

Let’s dive into how you can format specific types of code to make them optimized and readable.

HTML

  • Use consistent indentation for nested elements.
  • Ensure each tag is properly closed.
  • Avoid inline styles and scripts to keep your HTML lean.

CSS

  • Keep your properties alphabetically ordered for better readability.
  • Use shorthand properties where possible (e.g., margin: 10px instead of margin-top, margin-right etc.).
  • Separate sections with comments, like /* Typography */, to make the stylesheet more navigable.

JavaScript

  • Keep functions short and focused on a single task.
  • Use consistent indentation for blocks like if-else, loops, and functions.
  • Follow best practices like placing all variable declarations at the beginning of functions.

JSON

  • Properly format your JSON with consistent indentation (2 spaces recommended).
  • Always use double quotes for keys and strings.
  • Avoid trailing commas.
