REPL

Read-Eval-Print-Loop (REPL) is a simple, interactive computer programming environment that takes single user inputs (i.e. single expressions), evaluates them, and returns the result to the user.

The repl module provides a REPL implementation that can be accessed using:

• Assuming you have electron or electron-prebuilt installed as a local project dependency:

  ./node_modules/.bin/electron --interactive
  

• Assuming you have electron or electron-prebuilt installed globally:

  electron --interactive
  

Note: This only creates a REPL for the main process. You can use the Console tab of the Dev Tools to get a REPL for the renderer processes.
