Best online code editor for interviews is the solution to all the technical problems you face in an interview. Remember that an interview can be a very frightening experience if not managed well. The best thing that gives your confidence a boost is a good online code editor for interviews.
So, when doing coding interviews, I recommend using CodeFights platform. From what I see, it’s much better than other platforms in the market.
Theia
If you’re a die-hard SOLID fan and a nit-picking software architect, the Theia IDE will tickle your separation-of-concerns bone. It’s a TypeScript-coded (five points for style straightaway!) code IDE that has a perfectly separate front-end and backend. The front-end runs in a browser, while the backend can be anywhere — local machine or the cloud!
But that’s not all — the front-end can be run as an Electron app with a fully functional, isolated browser environment, giving you the look-and-feel of a native desktop app should you crave it.
Type12

Conclusion
I love coding challenges. I’ve been solving coding problems for a long time now and when I started getting interviews in software companies, I thought I was prepared. The reality was not the case. There’s a big difference in solving practice problems in a book or a website and taking part in an actual interview session. A lot of things that you don’t know will surface in this type of event and that’s why you can get stressed or frustrated easily.
