Visual Studio Code It has become an essential tool for millions of developers and programming enthusiasts. Although there are numerous code editors, few have matched the popularity and versatility of this software developed by Microsoft. If you've ever wondered what makes it so special, here you'll find a clear, in-depth, and up-to-date explanation, perfect whether you're a beginner or have been in the development world for years.

During the last years, Visual Studio Code (commonly known as VS Code) has won over the tech community for its ability to adapt to any environment. This is thanks to its lightweight nature, its wide range of features, and a community constantly creating extensions to work with any language or technology. Discover below how it works, what it's used for, and what its advantages are compared to other alternatives.

What is Visual Studio Code?

Visual Studio Code is an advanced, free, cross-platform source code editor developed by Microsoft. It was launched in 2015 with the goal of offering a lightweight yet powerful development experience, distinct from the heavier Visual Studio IDE. Since then, it has been constantly evolving, receiving new features and a huge number of extensions created by the community and Microsoft itself.

This editor is programmed primarily in TypeScript, JavaScript, and CSS, and uses technology Electron to run as a desktop application on Windows, macOS, and Linux systems. There's also a web version that allows you to edit code directly from your browser, adapting to different preferences and needs.

One of its main distinguishing features is its open source model, which has driven collaborative development and rapid adoption of VS Code. However, while its source code is open source (available under the MIT License), the official download includes some proprietary features under the Microsoft brand.

Since its inception, Visual Studio Code It has been acclaimed by the community for its ease of use, agile performance, and the ability to fully customize the development experience, something few editors achieve with such effectiveness.

What is Visual Studio Code used for?

VS Code is designed to be a flexible code editor, capable of adapting to both basic tasks and advanced workflows:

• Editing and development of any type of source code: from web pages in HTML, CSS and JavaScript, to complex applications in Python, Java, C++, Go, PHP, among hundreds of other languages.
• Integrated debugging: allows you to run code step by step, identify errors and fix them instantly, all without leaving the editor.
• Project management and version control: VS Code natively integrates version control with Git and other tools, making it easy to collaborate and track changes.
• Customization through extensions: Through its extensive Marketplace you can install additional tools, from code wizards to new themes or icons.
• Collaboration between teams: Thanks to features like Live Share, you can schedule in real time with other users, even if they are in different locations.

Visual Studio Code It can be the central hub for developing websites, APIs, microservices, automation scripts, mobile apps, desktop software, and much more. It achieves all of this thanks to a very solid foundation and the ability to expand it with thousands of specialized extensions.

Main features of Visual Studio Code

Next, we will go through some of the most important features that define VS Code and distinguish it from other similar editors.

IntelliSense and smart autocomplete

One of the reasons developers love VS Code is IntelliSense, an advanced auto-completion system that suggests variables, functions, methods, and code snippets as you type. In addition to speeding up your typing, IntelliSense helps avoid syntax errors and provides real-time descriptions about functions and parameters, which is ideal for working with unfamiliar libraries or APIs.

Integrated debugging

VS Code includes native debugging tools for a large number of languages:

• You can set breakpoints, examine variables, execute code line by line, and troubleshoot complex errors directly in the editor.
• Works as standard with JavaScript, Python, C++, C#, PHP, Java, and can be extended to many more through extensions.
• The entire debugging process is visual and integrated, eliminating the need to open external tools to analyze the execution flow of programs.

Version control with Git

La native integration with Git is one of VS Code's greatest assets. From the interface, you can commit, view code differences, create and switch branches, resolve conflicts, and manage entire repositories. There are also extensions such as GitLens which further enrich work with Git, helping you know who made what changes, and when they were made.

Extensibility and personalization

VS Code stands out especially for its focus on customizationThanks to its Marketplace, it is possible to:

• Add support for new programming languages.
• Install code analysis tools and linters, test wizards, and task automation.
• Apply visual themes and change the interface to your liking, improving the user experience.
• Create custom workflows by integrating terminals, custom keyboard shortcuts, and more.

Integrated terminal

It incorporates a terminal directly in the editor, which makes it possible to run commands, scripts, and applications without leaving VS Code. This feature is highly appreciated by those who work with command-line tools (such as npm, git, or automation systems) as it allows them to compile code, run tests, or manage development servers in a convenient and centralized manner.

Real-time collaboration

One of the most striking features is Live Share, an extension that allows you to share your work session with other developers, facilitating pair programming or simultaneous code review even from remote locations.

Project and work folder management

VS Code makes it easy to manage entire projects through a clear interface for organizing files and folders, as well as creating custom workspaces. Navigation is simple, even when the project is very large and contains many dependencies or modules.

Task automation

The editor supports the execution of scripts and automated tasks, such as compilations, file minification, unit tests or automatic deployments, integrating with tools such as Webpack, Gulp, Rollup and many more through extensions or direct configuration in the terminal.

Supported programming languages ​​and technologies

Natively, Visual Studio Code offers support for a wide list of languagesJavaScript, TypeScript, Python, C++, C#, PHP, HTML, CSS, JSON, Markdown, Go, Java, Ruby, among others. But its true strength is the ability to expand this support through extensions available in the Marketplace, which means there are virtually no limits when it comes to working with new languages ​​or frameworks.

• All major languages ​​currently have official or community-developed extensions, adding features such as autocompletion, debugging, refactoring, and code analysis.
• You can adapt the editor for frontend, backend, scientific development, or anything in between.

You can even use Visual Studio Code as a Markdown editor to write technical documentation or README files, taking advantage of syntax highlighting and integrated preview.

Key advantages of Visual Studio Code over other editors

Compared to other alternatives such as Atom, Sublime Text or the Visual Studio IDE itself, VS Code has differentiating advantages that have driven its global popularity:

• Light and fast: Its performance is excellent even on computers with modest resources. VS Code starts quickly and doesn't consume excessive resources, which is very important for those who need to compile or run heavy tasks.
• Easy to use, yet powerful: Its learning curve is very gentle. You can start programming in minutes, but also delve into advanced tools based on your needs.
• Absolute customization: Change the theme, icons, shortcuts, and editor behavior to suit your needs. If your workflow requires something specific, you can probably achieve it by configuring or installing the right extension.
• MultiplatformAvailable for Windows, Linux, macOS, and also via the web. No matter what operating system you use, your work environment will remain the same.
• Frequent updates and active community: It is a project in continuous development, with new versions every so often and a community that constantly contributes.

Comparison with other popular editors

To better understand why VS Code has been so successful, it's worth comparing it with other common alternatives on the market:

VS Code vs Atom

Atom For years, it was a favorite due to its open model and extensibility. However, VS Code surpasses it in performance, especially when handling large projects. Additionally, its native integration with key tools and more active community have led most developers to migrate to VS Code.

VS Code vs Sublime Text
