Writing clean and maintainable code is crucial for the success of any software project. Here are some best practices to follow:
Use Meaningful Variable Names
Choose variable names that clearly describe their purpose.
let userAge = 25;
let isLoggedIn = true;
Keep Functions Small
Each function should perform a single task. This makes your code easier to understand and maintain.
function calculateTotal(price, tax) {
return price + tax;
}
Write Comments
Comments help others (and yourself) understand your code. Use them to explain complex logic.
// Calculate the total price including tax
function calculateTotal(price, tax) {
return price + tax;
}
Follow Consistent Coding Style
Consistent formatting makes your code more readable. Use tools like Prettier or ESLint to enforce a coding style.
if (isLoggedIn) {
console.log("Welcome back!");
} else {
console.log("Please log in.");
}
By following these best practices, you’ll write code that is easier to read, understand, and maintain.
