How to Design Kotlin Extensions That Go Beyond Utility Functions!

As a developer, you’re likely familiar with the concept of utility functions in Java. These functions are used to perform specific tasks or operations that can be reused throughout your codebase.

Java-like Utility Functions ⚙️

In Java, utility functions are typically static methods within a class that provide a specific functionality (often named Utils, Helper, or something similar). They're often used to perform general-purpose tasks that don’t naturally belong to a specific class or type such as:

• String manipulation (e.g., isPalindrome, formatting)
• Date and time calculations
• Mathematical operations
• Data validation
