Editing in Nodes REPL Editor (opens in new tab)

The Node REPL has its own editor: node > .editor // Entering editor mode (Ctrl+D to finish, Ctrl+C to cancel) const increment = (array) => array.map(item => item + 1) increment([1,2,3]) Exit and evaluate with Ctrl+D: [ 2, 3, 4 ] I’d use this to experiment with JavaScript API’s without leaving my terminal-based IDE.
