# πŸ” Day 6-7: Built a React Password Generator β€” Mastered `useCallback`, `useEffect`, and `useRef`

As part of my React learning journey, I spent Day 6 and 7 building a simple but powerful Password Generator App . This wasn’t just a UI exercise β€” it was a deep dive into React hooks, especially useCallback, useEffect, and useRef.


What I Built

  • Password length control
  • Toggle numbers and special characters
  • One-click copy to clipboard
  • Auto-generate when options change

πŸ” Hooks I Focused On

useCallback

Memoized the password generation logic to avoid unnecessary re-renders β€” essential for optimization!

useEffect

Triggered re-renders when password settings changed. It was a great example of using useEffect for side-effect orchestration.

useRef

Used to grab the generated password and copy it to clipboard β€” direct and clean!
