## Calling a JavaScript Function from an HTML Body: A Comprehensive Guide

This tutorial will explore various methods of calling JavaScript functions from within the HTML body, covering different scenarios and best practices. We'll start with simple examples and gradually move towards more complex interactions, providing detailed explanations and code snippets along the way.

**Understanding the Relationship Between HTML and JavaScript**

Before diving into the specifics, it's crucial to understand the fundamental relationship between HTML and JavaScript:

* **HTML (HyperText Markup Language):** Provides the *structure* and *content* of a webpage. It defines elements like headings, paragraphs, images, and links.
* **JavaScript:** Adds *interactivity* and *dynamic behavior* to a webpage. It can manipulate HTML elements, respond to user actions, communicate with servers, and much more.

HTML and JavaScript work together. HTML creates the framework, and JavaScript breathes life into it. To make them interact, you need ways to "connect" the JavaScript code to specific elements or events within your HTML.

**Methods for Calling JavaScript Functions from the HTML Body**

Here are the primary ways to invoke JavaScript functions from within the HTML body:

1. **Inline Event Handlers:**
* **What they are:** Event handlers are attributes of HTML elements that define what should happen when a specific event occurs (e.g., a click, a mouseover, a form submission). Inline event handlers directly embed JavaScript code within these attributes.
* **How to use them:** You specify the event handler attribute directly within the HTML tag and set its value to a string containing the JavaScript code (usually a function call).
* **Example:**



* **Explanation:**
* The `button` element has an `onclick` attribute.
* `onclick="myFunction()"` means that when the button is clicked, the `myFunction()` function will be executed.
