Angular Interview Practice

When using innerHTML, which of the following is true?

1. It can only return plain text

2. It can return HTML tags as well

3. It cannot modify an element's content

4. It is limited to use with input elements only

The correct answer is: It can return HTML tags as well

Using innerHTML allows you to manipulate the HTML content of an element in the DOM. The primary functionality of innerHTML is to either retrieve or set the HTML markup contained within an element. When setting innerHTML, you can provide a string that includes not just plain text, but also HTML tags. This means you can dynamically create elements or structure through JavaScript by assigning HTML content to an element's innerHTML property. This capability is particularly beneficial when you need to insert styled content, create lists, images, or any other structured HTML directly into an element. For instance, using innerHTML, one could inject a new div or span element, or even a complete table, into a defined part of the webpage, making it a powerful tool for DOM manipulation. The other options either incorrectly define limitations or functionalities of innerHTML, which is designed specifically for both plain text and HTML content.
