Visual Studio Code—commonly known as VS Code—has become the most popular code editor in the world. Whether you are a beginner writing your first “Hello World” or a professional engineer building complex distributed systems, VS Code provides a powerful, flexible, and highly customizable development environment.
In this article, we take a deep dive into what makes VS Code so dominant, how to maximize its features, and the best extensions and workflows every developer should know in 2025.
What is Visual Studio Code?
Visual Studio Code is a free, open-source, lightweight, and cross-platform code editor created by Microsoft. It supports Windows, macOS, and Linux, and offers first-class support for JavaScript, TypeScript, and dozens of other languages.
But VS Code is much more than a simple text editor. With built-in debugging, Git integration, terminal support, extensions, and modern IntelliSense features, it competes directly with full IDEs like Visual Studio, PyCharm, WebStorm, and IntelliJ.
Why Developers Love VS Code
1. Lightweight yet Powerful
VS Code loads fast, consumes fewer system resources, and runs smoothly even on mid-range hardware. Despite being lightweight, it supports:
- Multi-language development
- Smart code completion
- Refactoring tools
- Debugging frameworks
- Modern UI and theming
2. Extensions for Everything
From Python and Java to C++, Rust, and Go—VS Code extensions transform the editor into a complete IDE.
Need linting? Testing? Docker integration? Kubernetes? Remote development?
There is an extension for every use case.
3. Built-in Git and GitHub Integration
You can stage changes, commit, push, pull, and handle merge conflicts—all inside the editor. With GitHub Copilot, the editor becomes even smarter by assisting with AI-generated code suggestions.
4. Cross-Platform + Sync
You can sync your VS Code settings across devices using:
- Settings Sync
- Extension sync
- Keybindings sync
- Snippets sync
This is essential for developers working on multiple machines.
5. Customization at Every Level
You can personalize almost everything inside VS Code:
- Themes
- Icons
- Fonts
- Keybindings
- Editor layout
- Workspace configurations
- Custom snippets
It adapts to your workflow—not the other way around.
Key Features You Should Be Using in 2025
1. IntelliSense & AI-Assisted Coding
VS Code’s IntelliSense gives real-time suggestions, type definitions, and auto-completion. With AI tools like GitHub Copilot, Tabnine, and Codeium, VS Code becomes a smart coding assistant.
2. Built-in Terminal
No need to switch back and forth between the editor and CLI. VS Code's integrated terminal supports PowerShell, Bash, Zsh, and Command Prompt.
3. Debugging Support
VS Code includes a powerful debugger for:
- JavaScript and TypeScript
- Node.js
- Python
- C++
- Java
- .NET
You can set breakpoints, watch variables, and step through execution easily.
4. Live Server & Live Preview
Frontend developers can preview changes instantly in the browser. With Live Share, you can collaborate with other developers in real time.
5. Explorer & Multi-Root Workspace
VS Code allows you to work on multiple projects at the same time in a single workspace—a critical feature for managing microservices or monorepos.
