REPL stands for Read Eval Print Loop and it represents a computer environment like a window console or unix/linux shell where a command is entered and system responds with an output. Node.js or Node comes bundled with a REPL environment. It performs the following desired tasks.
- Read – Reads user’s input, parse the input into JavaScript data-structure and stores in memory.
- Eval – Takes and evaluates the data structure
- Print – Prints the result
- Loop – Loops the above command until user press ctrl-c twice.
