This video tutorial explains how to use JavaScript techniques to manipulate web pages, focusing on implementing a counter that increments with each button click using the useState hook. The tutorial covers the syntax and functionality of useState, demonstrating how to manage state effectively. It highlights the dynamic updating of state values and concludes with a summary of the useState's power in state management.

What is the primary goal of the JavaScript technique discussed in the first section?

• To decrease a counter by one each time a button is clicked.

• To increase a counter by one each time a button is clicked.

• To reset a counter to zero each time a button is clicked.

• To double the counter value each time a button is clicked.

• The current state value remains unchanged.

• The current state value is reset to zero.

• The current state value automatically updates.

• The current state value is doubled.

What is demonstrated in the final section regarding the useState hook?

• The useState hook is ineffective for real-time changes.

• The useState hook can only be used for static data.

• The useState hook allows real-time state management.
