You can create multiple files at once using the terminal. This is a little nice trick, and it's so handy once you get used to it.
Open a new terminal window and type:
touch {component,style,test,index}.js
Great. If you run ls -l to see what happened you'll see that 4 files
have been created:
$ ls -l
total 0

-rw-r--r-- 1 telmo staff 0 Jan 13 15:43 index.js
-rw-r--r-- 1 telmo staff 0 Jan 13 15:43 style.js
-rw-r--r-- 1 telmo staff 0 Jan 13 15:43 test.js
Quick and easy!
