How can I create an online Javascript compiler to compile and execute Javascript real-time online? I'm building an interactive Javascript editor using Monaco editor but need ideas for compiler and real time output. Some ideas I have is an express app with babel compiler and use vm2 to run the code? Any more sophisticated ideas?
