- The output will be a webpage with the text: "Hello World"
- If we want to render a different view, we can use:
render "pages/home"- The file app/views/pages/home.html.erb will be used instead.
- We can pass variables to views using controller instance variables:
class UsersController < ApplicationController
def index
@name = "john"
respond_to do |format|
format.html { render }
end
end

And in the file app/views/users/index.html.erb you can use @name:
Hello <strong><%= @name %></strong>Clicking "Copy Code" button will copy the code into the clipboard - memory. Please paste(Ctrl+V) it in your destination. The code will get pasted.

And the output will be: "Hello john"
An important note around the render syntax, we can omit the render syntax entirely, Rails assumes that if we omit it. So:
class UsersController < ApplicationController
def index
respond_to do |format|
format.html { render }
end
end

Can be written instead as:
class UsersController < ApplicationController
def index
respond_to do |format|
format.html
end
end

Rails is smart enough to figure out that it must render the file app/views/users/index.html.erb.
