Most of the biggest companies in the world are tied to the world of technology. Google, Meta, Amazon and Alibaba, among others, have something in common: they offer digital products born on the Internet called web applications, the world is full of web applications, so learning how to create them has great value in the professional market. .
The two sides of the coin
Digital products like YouTube have, in a simplified sense, a visible face, what we call a user interface that lets you fill out forms or click on buttons and links.
It also has logic that allows users, for example, to create a profile, subscribe to channels, or search for a specific video among millions of uploaded videos. It’s the logic behind the visible part that makes the whole application work.
The visible part is known in programming as the Frontend. On the other hand, the logic that is behind and that makes everything work is called Backend, the union of these two components creates a digital product called a web application.
Developing the frontend and backend is a daunting task, which requires preparation and the right tools to get a valuable product. In fact, there are many programming languages and technologies that we can use to build them.
The main frontend technologies are HTML, CSS and JS, these three languages are the bases to build the frontend of an application.
- HTML: This allows us to create the structure of the website
- CSS: It is responsible for managing styles, colors and fonts.
In addition to languages, there are frameworks and libraries that allow us to develop the frontend in a more agile, complete and secure way.
The logical part of a web application can be compared to Amazon warehouses, where several systems help manage information and resources so that everything works properly.
For the backend, there is more variety when it comes to programming language, to name a few:
- Rubies on rails
Each of these programming languages depends on frameworks and libraries to be able to properly build a backend service, and the differences that make it possible to choose between one and the other lie in the type of web service to be offered, or the human talent available. .
