JavaScript course at Ubiqum

People considering starting a career in application development from scratch often wonder which languages they should learn from the over 675 known ones. The truth is that the decision is NOT very difficult. There are three languages that should be learned in any case if you want to pursue a career in IT, and those are the front-end languages: HTML, CSS and JavaScript. The first two are coding languages but not programming languages. HTML and CSS are languages understood by browsers, allowing us to give instructions for design and content we want to display to the user. They lack logical functions and are therefore not considered ‘programming.’ However, the next one, JavaScript, is a programming language and, for a beginner, after getting started with the two previous languages, JavaScript is necessary and essential.”

JavaScript, Why It’s Important

JavaScript is one of the most widely used coding languages in the world. In fact, without exaggeration, it’s fair to say that the entire web relies on JavaScript. For those unfamiliar with application architecture, applications are comprised of a front end, the part that interacts with the user, and a back end, the part that operates on the server. JavaScript is the quintessential front-end language. Alongside HTML and CSS, the languages understood by browsers, nearly all application front ends are programmed in JavaScript.

Daily-used applications such as Instagram, Facebook, and YouTube, among social networks, eCommerce virtual stores, and news websites, to name a few, are built with JavaScript. In essence, many websites of prominent brands use this language in their front end.”

JavaScript: The Language That Changed the Web

In May 1995, Brendan Eich invented a new programming language. He did it under tight deadlines. After 10 days with not much sleep, he presented the result to Netscape. It was the original version of JavaScript. The programming language that revolutionized the web, intended to be directly interpreted in the browser and written by both software developers and graphic designers.

Today, JavaScript stands as the most used programming language in the front end of applications and has held that position, according to Stack Overflow surveys, for the past ten years. JavaScript is what makes the web interactive. It’s accessible to beginners because you can write two lines of code and see the results immediately. In a sense, it democratizes learning because you don’t need to attend university to learn it. In fact, you don’t need to attend university to learn any programming language; that’s what code academies like Ubiqum are here for.

What is JavaScript?

In simple terms, JavaScript is a popular scripting programming language used to add interactive functionalities and other dynamic web content to web pages. Some well-known examples of JavaScript content include fillable forms, photo gallery presentations, and animated graphics.

Furthermore, JavaScript is relatively intuitive and easy to learn. It serves as an excellent starting point for those seeking to dive deeper into website development.

JavaScript represents the final layer of functionality in highly interactive websites. The front end of an application comprises elements programmed in the following languages:

HTML (Hyper Text Markup Language) provides the basic structure of the page. It’s the markup language we use to structure and give meaning to our web content—for instance, defining paragraphs, headers, data tables, or embedding images and videos on the page. CSS (Cascading Style Sheets) is your website’s fashion statement; it determines your site’s style. It formats and allows you to apply all the design ideas that designers have thought up and drawn. It’s a style rule language we use to apply style to our HTML content, like setting background colors, font types, and distributing content in multiple columns. JavaScript adds excitement. It brings the interaction and dynamism that users need. It’s a scripting language that allows you to create dynamically updating content, control multimedia, animate images, and essentially everything else you find on a website. These three layers complement each other seamlessly. When learning JavaScript, it’s crucial to understand the relationship between HTML, CSS, and JavaScript and how they come together to create a website. You’ll learn all of this in Ubiqum’s Web Development with JavaScript course.

Vanilla JavaScript

Vanilla JavaScript is a lightweight implementation of pure JavaScript without added libraries. Here, the term ‘vanilla’ refers to simple, pure JavaScript.

Many major companies use Vanilla JS, such as Google, Microsoft, Apple, Amazon, and others. Vanilla JavaScript is an excellent way to learn the fundamentals of programming in JavaScript before adding more advanced functionalities and features offered in libraries. At Ubiqum, you’ll spend three full weeks programming with vanilla.JS to solidify the basic programming concepts.

JavaScript Libraries (Frameworks)

A JavaScript library is a collection of pre-written code that performs certain functions. These libraries allow even novice users to quickly build useful websites. They save both novice and experienced users considerable time in constructing sites and applications.

While there are many JavaScript libraries, some of the most popular ones include REACT, Angular, and Vue. At Ubiqum, you’ll learn how to work with REACT.

Relationship Between JavaScript, APIs, and Other JavaScript Tools.
JavaScript is complemented by a series of tools (APIs and frameworks) that make website construction much more agile and efficient. All these elements are part of Ubiqum’s Web Development with JavaScript course.

  • Browser APIs: These are built-in browser constructs created with the JavaScript language, allowing much easier implementation of functionality.
  • Third-party APIs: These are constructs integrated into third-party platforms (for example, Twitter, Facebook) that allow you to use some of the platform’s functionalities on your web pages (such as displaying your latest tweets on your webpage).
  • JavaScript Libraries: Generally, one or more JavaScript files containing custom functions that you can add to your webpage to speed up or enable the writing of common functionalities.
  • JavaScript Frameworks: The next step beyond libraries, JavaScript frameworks (such as REACT and Angular) are typically packages of HTML, CSS, JavaScript, and other technologies that are installed and then used to write a complete web application from scratch.

In the Web Development with JavaScript course at Ubiqum, you will use all these elements in a coherent and systematic manner

JavaScript as a Backend Language

In recent years, JavaScript has exponentially advanced as a programming language. As we know, JavaScript was primarily used, and still is, to add interaction to our web applications, meaning it was only executed and interpreted by the web browser. However, everything changed with the release of Node.js. Node.js is a JavaScript code execution environment that uses V8, the Google Chrome engine written in C++, and was launched in 2009 by Ryan Dahl.

One of the best features of Node.js is its multi-platform capability. Thanks to this, we can execute JavaScript on any platform, whether it be on a server, desktop, mobile, or web.

Node.js, along with React, Mongo.db, and Express, forms the acronym MERN, which is the architecture that allows you to develop the backend of applications using JavaScript as the main language.

Now that you have all the information about JavaScript and why it’s a language you need to learn to start your career in software engineering, the Ubiqum Web Development with JavaScript/MERN course, which spans 480 hours in 12 weeks, teaches you all these languages and tools to kickstart your career in technology. Don’t worry, even if it seems very complex now, our course is designed for beginners. The vast majority of our students haven’t written a single line of code when they start at Ubiqum, and upon completion, they find jobs as software developers. If you want to verify this, talk to them and ask for their testimonials.
