Quiz App

Overview & Purpose

Quiz App is a practical JavaScript project that turns syntax into a working user-facing feature.

Syntax Guide

<button id="action">Run Quiz App</button>
<p id="output">Waiting...</p>

<script>
  const button = document.getElementById("action");
  const output = document.getElementById("output");

  button.addEventListener("click", () => {
    output.textContent = "Quiz App is working";
  });
</script>

Syntax Explanation: The code selects DOM elements, waits for a user event, then updates visible output. Larger versions add validation, persistence, API calls, or multiple state transitions.

Runnable Code Examples

<button id="action">Run Quiz App</button>
<p id="output">Waiting...</p>

<script>
  const button = document.getElementById("action");
  const output = document.getElementById("output");

  button.addEventListener("click", () => {
    output.textContent = "Quiz App is working";
  });
</script>

const features = ["Responsive layout", "Event handling", "Input validation", "Clear output", "Reset option"];
console.log(features);

localStorage.setItem("lastProject", "Quiz App");
console.log(localStorage.getItem("lastProject"));
