You're building a welcome message system for a website that greets users by their name. To do this, you'll combine multiple strings into one complete message.

1. Declare and initialize a variable named username with the value "Alice".
2. Declare and initialize another variable named welcomeMessage that combines the following parts in this exact order:
   • "Hello, "
   • the variable username
   • "! Welcome to our website."
3. Print (console.log) the contents of welcomeMessage.
