Some online compilers also support other languages such as HTML, CSS and others, making it a great tool for creating and testing web-based applications. Additionally, many online compilers also have a community feature where developers can share their code and get feedback from others.
- Debugging tools
- Live preview of the code output
- Option to save and share the code with others
- Syntax highlighting
- Integration with version control systems like GitHub
These compilers typically provide a text editor for writing code, and a way to run and test the code in a web browser. Some also offer additional features such as the ability to collaborate with others or to import and use external libraries. Another advantage is that online compilers are accessible from any device with an internet connection, making it easy for developers to work on their projects from anywhere. This allows for more flexibility in terms of where and when work can be done. Some online compilers also provide mobile apps for on-the-go coding.
