    <h2>Explanation</h2>
    <ul>
      <li><b>let age = 20;</b> — Declares a variable <b>age</b> with value 20.</li>
      <li><b>let day = "Tuesday";</b> — Declares a variable <b>day</b> with value "Tuesday".</li>
      <li><b>if (age >= 18) ... else ...</b> — Checks if <b>age</b> is 18 or older. If true, adds "Adult" to output; otherwise, adds "Minor".</li>
      <li><b>switch (day) ...</b> — Checks the value of <b>day</b> and adds a message to output depending on the day.</li>
      <li>The <b>output</b> variable collects the results and is displayed in the green output box above.</li>
