Exercise 152

• Create a new index152.js
• Define a user variable and assign a literal object with the following properties:
  • property: username, value: null
  • property: password, value: null
  • method: greet
  • method: updatePassword
  • method: updaterUsername
• The greet method shows the following message as output if username property is not null

  Hello, I'm user %username%
  

  • Else show the following output:

  Please assign a username value
  

• The updaterUsername accepts a string value as parameter
  • This method will set the username property value
  • You need to assign the parameter value to the username property
• The updatePassword accepts a string value as parameter
  • This method will set the password property value
  • You need to assign the parameter value to the password property
• Call the greet method (username and password are null at this point)
• Call updaterUsername passing a username value as string
• Call updatePassword passing a password value as string
• Call the greet method again (you should see the expected output)
