3. Use Snippets to Speed Up Coding

Snippets, or code templates, are an important and useful feature in Visual Studio Code (VSCode) that help make your coding faster and more efficient. Snippets are sets of code that can be customized for easy use—such as creating functions, setting up HTML, or commonly used code—by typing a short command or abbreviation that VSCode will auto-complete for you.

Using snippets helps save development time because you don’t have to repeatedly type the same code, such as functions for connecting to a database or basic HTML structures like <div>, <header>, or <footer>. With snippets, this code can be generated in just a few seconds.

How to Use Snippets in VSCode:

Using built-in snippets in VSCode
VSCode comes with pre-installed snippets for various programming languages such as JavaScript, HTML, CSS, Python, etc. By typing a shortcut and pressing Tab, the related code will be inserted automatically.

Examples:

• Type for and press Tab to get a JavaScript for loop.

• Type html and press Tab to get a basic HTML5 structure.

Creating your own snippets
If you often use specific code that isn’t included in the built-in snippets, you can create your own snippets by following these steps:

1. Go to the menu File > Preferences > User Snippets

2. Choose New Global Snippets file or select the snippets file for your desired language.

3. Add your custom snippet to this file. For example:

{
  "Log to Console": {
    "prefix": "log",
    "body": [
      "console.log('$1');"
    ],
    "description": "Logs output to the console"
  }
}

When you type log and press Tab, console.log() will be inserted.

Using snippets for automatic code formatting
Sometimes you may want your code to be clean and organized. Prettier is an extension that works with snippets to automatically format your code to a standard when saving the file.

Advantages of Using Snippets:

• Faster coding:
  Spend less time writing code with snippets that auto-complete frequently used code without the need to type it over and over.

• Reduce typing errors:
  Snippets help reduce errors, especially for repetitive code like functions, if-else statements, or closing tags in HTML.

• Customize snippets to suit your workflow:
  You can adjust snippets for your own use. If you work on a project that frequently uses specific functions or code, you can create a snippet and use it immediately.

• Improve team collaboration:
  Sharing snippets among team members improves collaboration. Everyone uses the same snippets, which makes the code more standardized and easier to understand.

Tips for Using Snippets Effectively:

• Set up snippets based on your project:
  If you work on a project with specific needs, such as app or web development, create snippets that will reduce coding time.

• Use existing snippets in VSCode:
  If you’re a beginner, VSCode provides built-in snippets you can use right away and also customize to better suit your needs.

• Organize your snippets for convenience:
  Use clear and understandable names for your snippets to make them easier to find and use. For example, use log for console.log().

• Learn from others:
  If working in a team, try sharing snippets with teammates to make work more convenient for everyone.

4. Use IntelliSense for Auto Completion

IntelliSense is an important feature that makes Visual Studio Code (VSCode) stand out from other editors. It helps make coding more convenient and faster. This feature provides auto completion for the code you type, so you don’t have to write everything manually, which saves time and increases typing accuracy.
