Writing clean code is an important aspect of software development, as it makes the code more maintainable, readable, and scalable. However, it is not uncommon to see code written in a way that does not follow the best practices of clean coding.
Here is an example of a code in JavaScript/TypeScript that contains 10 common mistakes that violate clean code principles:
function x(a,b){
var c=a+b;
return c;
}
function y(x,z){
return x*z;
}
function z(x,y){
var p=x(y);
return p;
}
The same code, rewritten with clean code principles in mind, would look like this:
function addNumbers(a: number, b: number): number {
const result = a + b;
return result;
}
function multiplyNumbers(x: number, z: number): number {
return x * z;
}
function processNumbers(processFunction: (num: number) => number, x: number): number {
const result = processFunction(x);
return result;
}
Here are the benefits of using clean code principles in the rewritten code:
Improved readability: The code is much easier to read, understand, and follow.
Increased maintainability: The code is more maintainable, as it is less prone to bugs and easier to update.
Better organization: The code is organized in a logical way, making it easier to navigate and maintain.
Enhanced scalability: The code is scalable, as it can easily be extended and integrated with other parts of the application.
Better code reusability: The code is reusable, as it can be used in other parts of the application without modification.
Enhanced debugging: The code is easier to debug, as errors and bugs can be easily traced and fixed.
Improved performance: The code is more performant, as it is optimized for efficiency.
Better collaboration: The code is easier to collaborate on, as multiple developers can understand and work with it more easily.
Improved documentation: The code is easier to document, as it is clear and self-explanatory.
Better overall quality: The code is of higher quality, as it adheres to best practices and standards.
And that's it ! See U next level Doobs !
