Overview

This PR refactors the useCounter hook by extracting the validateValue function outside the hook and removing unnecessary memoization to improve performance and code maintainability.

Reason for Change

The previous implementation had several inefficiencies:

  1. Unnecessary memoization overhead: The validateValue function was wrapped with useCallback and then memoized again, creating unnecessary computational overhead
  2. Memory inefficiency: Each hook instance created its own validateValue function, leading to redundant function creation
  3. Complex dependency chain: The memoized validation function created an indirect dependency chain that was harder to track

Changes Made

  • Extracted validateValue function outside the hook as a pure function
  • Removed unnecessary useCallback for validation logic
  • Simplified dependency arrays by directly depending on [min, max]
  • Improved type safety with Omit<UseCounterOptions, 'step'>
  • Enhanced code readability and maintainability

Checklist

  • Did you write the test code?
  • Have you run yarn run fix to format and lint the code and docs?
  • Have you run yarn run test:coverage to make sure there is no uncovered line?
  • Did you write the JSDoc?
