JavaScript is a programming language that has been used by developers to create interactive web pages, mobile apps, and simple video games. This is the only programming language that runs on all browsers, in addition to powering many of today's most popular sites, such as Facebook, Google Maps and YouTube.

The technology present in the development through JavaScript is incredible and from it comes all its importance, especially for professionals in software development and programming. Its functionality involves a series of processes, such as:

- Build interactive websites;
- Create animations;
- Develop mobile applications;
- Create video games;
- Perform calculations on datasets.

The importance of the JavaScript language to the programmer can be explained by the fact that it has made web development more accessible to developers of all skill levels, as well as allowing developers to create powerful interactive applications with less code than other languages.

JavaScript is also responsible for allowing programmers to create more responsive mobile apps more intuitively while improving the quality of the product delivered to the customer.

In this article, you will understand more about the importance of JavaScript for every programmer and what are the main foundations of this language. Also, check out a little bit about the future of JavaScript in the software development process.


With JavaScript you can implement complex items on a web page, for example display content that updates over time, interactive maps or animated 2D/3D graphics, etc. For that, it works very well with HTML and CSS, as you can see in the picture below.
Here's a summary of how JavaScript, HTML, and CSS work together:

- HTML is the markup language we use to structure and give meaning to our web content. For example, defining paragraphs, headings, tables of contents, or inserting images and videos on the page.

- CSS is a style rules language that we use to style our HTML content. For example, setting background colors and fonts, and positioning our content in multiple columns.

- JavaScript is a programming language that allows you to create dynamically updating content, control multimedia, animated images, and everything else interesting. Okay, not everything, but it's wonderful what you can accomplish with a few lines of JavaScript code.


JavaScript is one of the most popular programming languages in the world. It has been around for nearly three decades and has evolved to become a powerful language used in web development, server-side programming, and even mobile applications.
