How to Use VS Code: Everything You Need to Know
You have probably heard the buzz. Visual Studio Code—or VS Code, as most of us call it—has taken the development world by storm. But why? Walk into any developer’s office, glance at their screen, and chances are you will see that familiar blue icon staring back at you.
I remember my first time opening VS Code. Honestly, I felt overwhelmed. Tabs, icons, a blinking cursor, and a sidebar full of mysteries. However, I quickly discovered something surprising: this powerful tool welcomes beginners with open arms.
So, today, I will show you how to use VS Code effectively. You do not need a computer science degree. You just need curiosity and a willingness to explore.

Getting Started VS Code: The First Launch
First, download VS Code from the official website. The installation process takes only a minute. Once you finish, open the application. As a result, you will see a clean, minimalist interface.
Now, take a deep breath. For your reference, the interface is divided into five main areas:
- The Activity Bar on the far left
- The sidebar next to it
- The Editor in the center
- The Panel at the bottom
- Then, the Status Bar at the bottom
Think of these as your command center. Each part serves a specific purpose, and you will learn them gradually.
Open Your First File or Folder
To get started, click “File” in the top menu, then select “Open Folder.” Choose any folder from your computer. In response, VS Code will display its contents in the Side Bar. Alternatively, drag and drop a folder directly into the editor. Either way, the application responds instantly.
Why start with a folder? Well, VS Code treats folders as projects. This approach helps you organize your work logically. As a result, you can switch between projects effortlessly.
The Editor: Your Creative Playground
Next, click on any file in the Side Bar. Consequently, the file opens in the Editor. Start typing. Notice the syntax highlighting? VS Code automatically colors your code, making it readable and reducing errors.
Moreover, you can open multiple files simultaneously. Each file appears as a tab. Drag tabs to rearrange them. Additionally, split the editor by pressing Ctrl + \ (or Cmd + \ on Mac). Suddenly, you can view two files side by side. This feature proves invaluable when comparing code or referencing documentation.
Transitioning between files becomes second nature. For instance, press Ctrl + Tab to cycle through open files. Then, your fingers learn these shortcuts, and your productivity soars.
The Command Palette: Your Magic Wand
Now, press Ctrl + Shift + P. A small input box appears at the top of the screen. Then, this is the Command Palette, and it changes everything.
Type anything you want to do. Want to change your color theme? Type “theme.” Need to install an extension? Type “extensions.” In short, the Command Palette lists every action available. You do not need to memorize menus. You need to know what you want.
I use the Command Palette dozens of times daily. As a result, it keeps my hands on the keyboard and my mind on the code.
Extensions: Supercharge Your Workflow
Vanilla VS Code offers plenty of features. However, extensions transform it into a tailored powerhouse.
To begin, click the Extensions icon in the Activity Bar (it looks like four squares). Search for what you need. Here are my top recommendations:
- Prettier: Firstly, this extension automatically formats your code. Consequently, no more manual spacing or alignment.
- ES7+ React/Redux/React-Native snippets: Secondly, if you work with React, this extension saves hours of typing.
- Live Server: Thirdly, launch a local development server with one click. As a result, your HTML and CSS changes appear instantly in the browser.
- GitLens: Understand your Git history without leaving the editor.
- Python: Then, Microsoft’s official Python extension offers IntelliSense, debugging, and environment management.
Install only what you need. Too many extensions slow down performance. Therefore, start small, then add more as your workflow demands.
VS Code: Mastering the Integrated Terminal
Meanwhile, look at the bottom of your screen. See the word “TERMINAL”? Click it, or press Ctrl + `. Then, a terminal opens inside VS Code.
Moreover, this terminal connects directly to your system’s command line. As a result, you can run scripts, install packages, commit to Git, and start servers—all without switching windows.
I love this feature. Previously, I constantly jumped between my editor and a separate terminal window. Now, everything lives in one place. Furthermore, the terminal respects your current folder, so navigating feels intuitive.
Git Integration: Track Changes Seamlessly
In addition, VS Code integrates Git natively. To begin, open the Source Control view from the Activity Bar (the third icon). If your folder contains a Git repository, you will see all changes listed.
Stage changes by hovering over a file and clicking the plus icon. Next, write a commit message in the input box. Then, press Ctrl + Enter to commit. Push, pull, and branch directly from the interface.
You do not need to memorize complex Git commands. VS Code handles the complexity. However, if you prefer the terminal, the option remains available.
VS Code: Customize Your Environment
Similarly, VS Code adapts to you. Go to File > Preferences > Settings. Then, you will find hundreds of options. For example, change the font size, adjust the tab size, or toggle word wrap.
Prefer a dark theme? Then, open the Command Palette, type “color theme,” and browse the options. Likewise, you can even install custom themes from the Extensions marketplace.
I set my font to 14px and enable “word wrap” for markdown files. As a result, these small tweaks make long sessions comfortable.
VS Code Debugging: Find and Fix Errors
Moving on, click the Run and Debug icon in the Activity Bar (the play button with a bug). Then, press “create a launch.json file” to configure your debugger.
Once configured, set breakpoints by clicking to the left of a line number. After that, press F5 to start debugging. VS Code will execute your code and pause at breakpoints. Consequently, you can inspect variables, step through functions, and watch expressions.
Debugging feels intimidating at first. However, once you learn it, you will wonder how you ever lived without it. No more scattered console.log statements. Instead, you gain precise control over your code’s execution.
Keyboard Shortcuts: Work Faster
Now, let’s talk about shortcuts. They accelerate your workflow. Here are essential ones:
| Action | Windows/Linux | Mac |
|---|---|---|
| Open Command Palette | Ctrl + Shift + P | Cmd + Shift + P |
| Open Terminal | Ctrl + ` | Cmd + ` |
| Split Editor | Ctrl + \ | Cmd + \ |
| Find | Ctrl + F | Cmd + F |
| Save All | Ctrl + K S | Cmd + K S |
| Go to File | Ctrl + P | Cmd + P |
| Toggle Side Bar | Ctrl + B | Cmd + B |
Memorize these one at a time. Then, choose one shortcut each day and use it consistently. In a week, your hands will move without thinking.
Working with Multiple Cursors
Here is a trick that feels like magic. Press Alt + Click (or Option + Click on Mac) to place multiple cursors. Then, type once, and the text appears at every cursor position.
Need to edit several lines simultaneously? Firstly, select a block of text. Next, press Ctrl + Shift + L. VS Code places a cursor at the end of each selected occurrence. As a result, rename variables instantly. Add prefixes to multiple lines. This feature alone saves me hours each month.
IntelliSense: Your Coding Assistant
Start typing a function or variable name. Immediately, VS Code displays suggestions in a dropdown menu. This is IntelliSense. It learns from your code and from language extensions.
Moreover, press Tab or Enter to accept a suggestion. In turn, the editor fills in the rest. Moreover, IntelliSense also shows function signatures, parameter lists, and documentation. It reduces typos and speeds up development significantly.
Snippets: Write Less, Do More
Type for in a JavaScript file and press Tab. VS Code expands it into a full for loop. These are snippets—predefined code templates.
You can create your own snippets, too. Then, open the Command Palette and type “snippets.” Then, choose “Configure User Snippets.” Select a language, and finally define your snippet. For example, I created a snippet for React functional components. Now I type rfc and press Tab, and the entire component structure appears.
Settings Sync: Keep Your Configuration Everywhere
Do you use VS Code on multiple machines? If so, enable Settings Sync. Click the gear icon in the bottom-left corner, then select “Turn on Settings Sync.” After that, sign in with your GitHub or Microsoft account.
VS Code saves your settings, extensions, and keybindings to the cloud. Therefore, when you open VS Code on another computer, everything syncs automatically. Then, no more rebuilding your setup from scratch.
