Writing maintainable and easy-to-read code should be every developer’s priority. One technique that helps accomplish this goal is implementing early return patterns in JavaScript. By returning from functions earlier than expected, you eliminate nested indentation levels while making code flow smoother and more predictable.

This article explores the benefits of early returns, along with practical code examples demonstrating various scenarios.

Why Use Early Returns?

When developing applications, it’s common to encounter situations where multiple exit points exist within a function. Without proper handling, complex conditional statements could result in deeply nested structures, which often lead to confusion and increased maintenance costs. Applying early returns simplifies these scenarios significantly, providing several advantages:

• Improved Readability: Reducing nesting depth enhances legibility, allowing developers to quickly grasp the purpose and structure of a given function.
• Reduced Cognitive Overhead: Fewer layers mean less mental energy expended during…
