JavaScript Basics

JavaScript is a programming language that allows you to add interactivity and dynamism to web pages. With it, you can create animations, validate forms, manipulate HTML elements, and much more.

To start using JavaScript, you need to include the code inside the tags. The code can be inserted directly in the HTML file or in a separate file with a .js extension.

One of the key features of JavaScript is its ability to manipulate HTML elements. For example, you can change the content of an element, change its color, position or even create new elements.

In addition, JavaScript also allows user interaction with the page. It is possible to create buttons that, when clicked, trigger a function that performs a certain action. It is also possible to create forms that validate the data entered by the user before sending the information to the server.

Another interesting feature of JavaScript is the ability to create animations and visual effects. You can create transition animations between pages, sliding menus, parallax effects and much more.

To delve deeper into JavaScript, it's important to study concepts such as variables, functions, conditionals, and loops. With these elements, it is possible to create more complex and dynamic programs.

In summary, JavaScript is an essential programming language for anyone who wants to create interactive and dynamic web pages. With it, it is possible to manipulate HTML elements, create interactions with the user, validate forms, create animations and visual effects, among other functionalities.
