Code Formatting Best Practices
Code formatting enhances readability and maintainability of code. Follow these practical steps to format your code effectively:
Consistent Indentation:
- Use consistent indentation to create a hierarchical structure.
- Use 2 or 4 spaces (avoid tabs) for each indentation level.
- Align opening and closing curly braces vertically.
Proper Spacing:
- Leave a space after commas, semicolons, and assignment operators (=).
- Put spaces around logical operators (&&, ||, etc.).
Line Breaks:
- Insert line breaks to improve readability.
- Break long lines after operators to enhance comprehension.
- Avoid unnecessary line breaks that disrupt the flow of the code.
Example in JavaScript:
// Function to calculate sum of two numbers
const sum = (a, b) => {
// Check if either number is null or undefined
if (a == null || b == null) {
throw new Error('Input cannot be null or undefined');
}
// Return the sum of the two numbers
return a + b;
};
Benefits of Code Formatting:
- Improved readability: Easier to understand and follow code logic.
- Increased maintainability: Simplifies code changes and debugging.
- Enhanced collaboration: Makes it easier to collaborate with others on code projects.
