Ruby: Difference between require and load

Load

• loads a file (you were right!)
• As it loads a file, it has to have the extension and a path depending on its location

File:

hello.rb

    p 'Hi there'   
  
  

File:

test1.rb

    load 'hello.rb'
    p 'Willma'
  
  

Require

• require is smarter than load.
• It loads a library and prevents you to load it twice. If you try to do so... it will print "false" like saying "dumb" to you.
• You don't need to specify the rb extension. You can include the path depending on its location

File:

hello.rb

    p 'Hi there'   
  
  

File:

test1.rb

    require 'hello'
    p 'Willma'
