How do you "create a .js file" ?

[Pauuulooo]

I still haven't figured out how you create a .js file when he says "Then, create a new .js (e.g bot.js) file with the following contents:" . I'm using a Mac, so IOS I guess, and I can't figure out if I need to create that folder on my computer or somehow find a way to create it on the facebook developers page...

Hey Pauuuloooo,

Create a .js file is just simply using a text editor and creating a new file and name it "bot.js" on your computer. In this script contains the actual logic of your tinderbot. You execute the script on the command line with this command: node bot.js.

Hope that helps!
