Prompt Title: Difference between innerHTML and textContent.

The usage of innerHTML and textContent depends on the specific requirements of your code and how you want to handle the content being set. Here's a summary of when to use each property:

1. Use innerHTML when:
   • You need to insert HTML markup within an element, and you want the browser to parse and render the HTML correctly.
   • You have full control over the content being set, and there is no risk of injecting user-generated content that could lead to security vulnerabilities like Cross-Site Scripting (XSS) attacks.

Example:

javascriptCopy code
let div = document.createElement('div');
div.innerHTML = '<strong>Hello</strong> world!';

2. Use textContent when:
   • You only need to insert plain text content without any HTML markup.
   • You are working with user-generated content or content from an untrusted source, and you want to mitigate the risk of XSS attacks. Using textContent ensures that any HTML tags in the content will be treated as plain text and not rendered as HTML.

Example:

javascriptCopy code
let div = document.createElement('div');
div.textContent = '<strong>Hello</strong> world!';

In summary, use innerHTML when you need to work with HTML content and have no security concerns, and use textContent when you need to work with plain text content or need to handle user-generated content safely.
