Execute Javascript in Sinatra

Question

I searched a lot but I can't seem to find a clear answer about how to execute javascript code via Sinatra, it symply renders the code as html for me. Here is what I tried so far :

require 'sinatra'
set :public_folder, 'public'
class Dashboard < Sinatra::Base
 get '/' do
 send_file File.join(settings.public_folder, 'javascripts/index.js') # renders code as html
 '<script type="text/javascript" src="index.js"></script>' # nothing
 '<script>alert("Hello, world !")</script>' # works correctly
 end
end

• Legendary: render js: '<script type="text/javacript" >alert("q");</script>' try pls
• Kernael: "wrong number of arguments (1 for 2..4)", also just '<script>alert("hello")</script>' is working, but I'm really trying to load a script from a file here

Answer 1

Figured it out, the path in src must be so :

<script type="text/javascript" src="javascripts/index.js"></script>
