About Lesson
In React, you can easily implement hiding, showing, or toggling elements based on user interaction by manipulating the component’s state.
Key Concepts:
-
Show/Hide:
- Use a boolean state variable to control whether an element is visible or not.
- Conditionally render elements based on the state.
-
Toggle:
- Use a function to toggle the boolean state, switching between showing and hiding the element.
Example Approach:
- State Initialization: Use
useState
to create a state variable, e.g.,isVisible
. - Conditional Rendering: Use an
if
statement or ternary operator to decide whether to display the element based on the state. - Toggle Function: Use a function to toggle the state when a button is clicked, updating visibility.
This approach allows for smooth user interaction and dynamic content visibility in React applications.
