Question

Consider the following code segment: <h2 id = "banner"> Welcome to my site! </h2> What will be returned if the command document.getElementById("banner") is executed? <h2> Welcome to my site! </h2> Welcome to my site! banner <h2></h2> undefined

Answer 1

When the command `document.getElementById("banner")` is executed, it will return the DOM element with the specified ID.

In this case, it will return the `<h2>` element that has the ID "banner":

```html
<h2 id="banner"> Welcome to my site! </h2>
```

However, if the element was found, it is returned as an object representing that element, not as a string or any other data type.

If you wanted to extract the text content of the element, you would access the `.textContent` property or `.innerHTML` property of the returned element.

So in this case, the command would return the actual `<h2>` element:

```html
<h2 id="banner"> Welcome to my site! </h2>
```

But in the context of the options you provided, since only the literal options are available (without the actual HTML element being represented), the closest correct interpretation would be that it returns the element, and so the answer should be interpreted as:

```html
<h2> Welcome to my site! </h2>
```

To summarize, the output of `document.getElementById("banner")` is the `<h2>` element itself and does not match any of your listed outcomes directly. The expected conceptual result is the DOM element `<h2 id="banner"> Welcome to my site! </h2>`.

Given the exact choices you provided, none of them precisely matches the raw return value. If you were looking strictly at output made by a console or a string representation of that object in some environments, it might not be represented in the answer options. So amongst the provided options, understanding that it's returning the element would lead to the understanding that none fit exactly.
