Can javascript control the GPIO of a raspberry pi?

Question

I'm building a simple robot. I'm wanting to interface with it in a Web page hosted on the pi. I just need a camera and a few buttons to control motors.

Answer 1

you can control the gpio of a raspberry pi via command line.
this means you can send these commands from a nodejs server installed on your rpi.
a js client could trigger such commands using sockets (socket.io) to communicate with the server
edit: look at what i found
https://www.npmjs.com/package/rpi-gpio

Answer 2

Strictly speaking Python is the way to go controlling the pi's GPIO. However there are some packages available (like NodeJS) that allows you to use javascript to acces the GPIO.
