<pre><code class="lang-javascript">undefined ? "print" : "not print"
</code></pre>
is a ternary operator in JavaScript. The ternary operator works as follows:
<pre><code class="lang-javascript">condition ? expressionIfTrue : expressionIfFalse
</code></pre>
<ul>
<li>If the <code>condition</code> evaluates to <code>true</code>, it returns <code>expressionIfTrue</code>.
</li>
<li>If the <code>condition</code> evaluates to <code>false</code>, it returns <code>expressionIfFalse</code>
</li>
</ul>
<h3 id="heading-explanation">Explanation:</h3>
The condition is <code>undefined</code>:
In JavaScript, <code>undefined</code> is a falsy value. This means it is treated as <code>false</code> in boolean contexts.
What happens in the ternary operator?:
The condition <code>undefined</code> evaluates to <code>false</code>.
Since the condition is <code>false</code>, the operator will return the second expression, which is <code>"not print"</code>
Output:
<pre><code class="lang-javascript">"not print"
</code></pre>
This is because <code>undefined</code> is falsy, and the ternary operator selects the expression after the colon (<code>:</code>) when the condition is false.

```javascript
undefined ? "print" : "not print"
```

is a **ternary operator** in JavaScript. The ternary operator works as follows:

```javascript
condition ? expressionIfTrue : expressionIfFalse
```

* If the `condition` evaluates to `true`, it returns `expressionIfTrue`.
    
* If the `condition` evaluates to `false`, it returns `expressionIfFalse`
    

### Explanation:

**The condition is** `undefined`:

In JavaScript, `undefined` is a **falsy value**. This means it is treated as `false` in boolean contexts.

**What happens in the ternary operator?**:

The condition `undefined` evaluates to `false`.

Since the condition is `false`, the operator will return the second expression, which is `"not print"`

Output:

```javascript
"not print"
```

This is because `undefined` is falsy, and the ternary operator selects the expression after the colon (`:`) when the condition is false.

The expression undefined ? "print" : "not print" evaluates to "not print" because undefined is a falsy value in JavaScript. In a ternary operator, if the co

undefined ? "print":"not print" what is output...?
