Where is Client-side JavaScript code is embedded within HTML document(s) ?

Client-side JavaScript code is embedded within HTML documents in the following ways:

1. Inline JavaScript: This is when JavaScript code is written directly within the HTML tags. It is usually placed between the <script> tags. For example:

<script>
  alert("Hello, World!");
</script>

2. External JavaScript: This is when JavaScript code is written in a separate file (with a .js extension) and then linked to the HTML document using the src attribute in the <script> tag. For example:

<script src="script.js"></script>

In the above example, "script.js" is the external JavaScript file.

3. Event Handlers: JavaScript can also be embedded in HTML by using event handlers. These are attributes that can be added to HTML elements to define what JavaScript code should run when an event occurs. For example:

<button onclick="alert('Hello, World!')">Click me</button>

In the above example, when the button is clicked, the JavaScript code within the onclick attribute is executed.
