Code Formatting Made Simple: Exploring .editorconfig

1. Create or Locate the File: In the root directory of your project, create a file named `.editorconfig`.
2. Specify Coding Conventions: Inside the file, you'll define the coding conventions using a simple syntax. Each rule consists of a property followed by its value, separated by an equal sign. 
   • Here's a basic example:

   • # Set the root as the default
     root = true
     
     # Define a coding style for all files
     [*]
     indent_style = space
     indent_size = 2
     charset = utf-8
     trim_trailing_whitespace = true
     insert_final_newline = true
     
     # Define a specific coding style for JavaScript files
     [*.js]
     indent_size = 4

3. Rule Sections: Rules can be defined globally, for specific file types, or even for specific directories. Use wildcard patterns to match file types (e.g., `*.js` for JavaScript files), and use relative paths to target directories (e.g., `src/*` for all files in the `src` directory).

• `indent_style` and `indent_size`: These properties control the indentation style and size. Choose between `tab` or `space` for `indent_style` and specify the number of spaces for `indent_size`.

# Use tabs for indentation
indent_style = tab

# Use 4 spaces for indentation
indent_style = space
indent_size = 4

• `charset`: Define the character encoding for your files.

# Use UTF-8 character encoding
charset = utf-8

• `end_of_line`: Specify the line ending style.

# Use LF (Unix-style) line endings
end_of_line = lf

# Use CRLF (Windows-style) line endings
end_of_line = crlf

• `trim_trailing_whitespace`: Remove trailing whitespaces at the end of lines.

# Trim trailing whitespaces
trim_trailing_whitespace = true

• `insert_final_newline`: Ensure a newline character at the end of the file.

# Insert a final newline
insert_final_newline = true

1. Consistency: Developers using different editors or IDEs will follow the same coding standards.
2. Reduced Friction: Minimize debates about coding styles within the team.
3. Ease of Onboarding: New team members can quickly adopt the project's coding conventions.
4. Version Control: `.editorconfig` files can be versioned, ensuring that coding styles evolve with the project.

• Visual Studio Code: Install the "EditorConfig for VS Code" extension.
• IntelliJ IDEA: Enable the "EditorConfig" plugin from the plugin marketplace.
• Sublime Text: Install the "EditorConfig" package via Package Control.
