HTML JavaScript

HTML and JavaScript are two programming languages that are commonly used together to create dynamic and interactive web pages. HTML, which stands for Hypertext Markup Language, is the language used to create the structure and content of a webpage. It defines the elements of a page, such as headings, paragraphs, links, and images, and organizes them into a hierarchical structure.

JavaScript, on the other hand, is a scripting language that can be used to add interactivity and dynamic behavior to HTML pages. With JavaScript, you can create animations, validate user input, manipulate the DOM (Document Object Model), and interact with APIs (Application Programming Interfaces) to fetch and display data.

In below example, we’ve defined a JavaScript function called greetUser() that prompts the user to enter their name and then displays a greeting using an alert dialog. We’ve also added an HTML button element that calls the greetUser() function when it’s clicked.

When the user clicks the button, the JavaScript function is executed and the prompt and alert dialog boxes are displayed, allowing the user to enter their name and receive a greeting.

By combining HTML and JavaScript, you can create powerful and interactive web pages that engage your users and provide a great user experience.
