Set up a live code editor in Next.js with CircleCI
Interactive playgrounds have changed the way developers learn and experiment with code. Instead of having to copy and paste code into a separate Read–Eval–Print Loop (REPL) or local environment, users can write, edit, and run code directly within the tutorial or application interface. Adding this type of editor to a Next.js app makes it more engaging and helps users understand better by eliminating the need to switch between different tools.
