Using plain javaScript instead of coffeeScript

Question

Does my ruby on rails app have to use coffeeScript or could I can I Just use plain javaScript?

• Sam: remove .coffee from the end of your file and it runs plain js. so application.js.coffee -> application.js

Answer 1

You need to ensure not having the same filename both in javascript and coffeescript.

For example: having both the files

assets/javascripts/application.coffee 
assets/javascripts/application.js 

will only get the coffeescript loaded.

Answer 2

Yes, you can just use Javascript. You have your files in app/assets/javascripts/*.js . On local dev, do a view source and you will see your files there.

On production, the Asset Pipeline will concatenate and minify.

Answer 3

You can also write plain JS in CoffeeScript files, just put ` around it:

hi = `function() {
 return [document.title, "Hello JavaScript"].join(": ");
}`

• user2553863: In other words, you can have BOTH JS and CoffeeScript in the same .coffee file, if you enclose your JS code in backticks. Thanks, Qasim.

Answer 4

you can write whatever you want jquery or javascript just make sure the extension for that is js
