Benefits of using online code editors

  1. No software installations required => Being a developer you may know that before getting started with any frameworks there is always one thing that we have to do is to install the dependencies and libraries and it also has compatibility issues. So in the case of online code editors, it’s all taken care and you can directly start coding.
  2. Code sharing and collaboration => Yeah, I know we have git and bitbucket for it, but in online code editors, you can share the code with anyone with just a single click. 
  3. Asset hosting => You can host your files: [images, scripts, etc] on their domain.
  4. Evaluation test => While interviewing candidates remotely, you can share code assignments directly and ask them to code while screen sharing. 
  5. Teach new learners => If you are a teacher and tired of installing dependencies and switching windows of code & output while teaching then you can simply code in online code editors and everything will be inside a single window.

Conclusion

We have seen the 5 best online Code Editors in 2021 so far. Out of these 5 editors my personal favorite is CodeSandbox because it offers great features and it is very handy. However others in a list are also best at their levels.
