The Coder’s Computer

Four important features in a Text Editor

• Code completion — provides suggestions based on what you type, saving time and reducing typos.
• Syntax highlighting — colorizes code to improve readability and error-spotting.
• A good selection of themes — lets you customize background and text colors (e.g., dark mode to reduce eye strain).
• Support for extensions — add-ons that enhance functionality and allow the editor to grow with your needs.
