Most of the top companies in the world are related to the world of technology. Google, Meta, Amazon, and Alibaba, among others, have something in common: they offer digital products that were born on the internet called web apps, the world is full of web apps, so learning to create them has a high value in the professional market.
The two sides of the coin
Digital products such as YouTube have, in a simplified sense, a visible face, what we know as a user interface that allows you to fill out forms, or click on buttons and links.
It also has a logic behind it that allows users to, for example, create a profile, subscribe to channels, or search for a specific video among millions of uploaded videos. It is the logic behind the visible part that makes the whole application work.
The visible part is known in programming as 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 frontend and backend is an arduous task, which requires preparation and the right tools to achieve 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 basics to build the frontend of an application.
- HTML: This allows us to create the structure of the website
- CSS: It is in charge of 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 logic part of a web application can be compared to the Amazon warehouses, where there are multiple systems that allow managing the information and resources so that everything works properly.
For the backend there is more variety with respect to which programming language, to name a few:
- Ruby on Rails
Each of these programming languages depends on frameworks and libraries to be able to build a backend service correctly, and the differences that allow you to choose between one and another lie in the type of web service to offer, or the human talent available.
