A source code editor is a specialized text editor designed for writing and editing computer code. These editors provide features like syntax highlighting, which colors code elements to improve readability, and code completion, which suggests possible code snippets as you type. They support various programming languages, making them essential tools for developers. Many source code editors also include debugging tools, version control integration, and customizable interfaces. Popular examples include Visual Studio Code, Sublime Text, and Atom. These features help streamline the coding process, allowing programmers to write, test, and refine their code more efficiently.
