18,322 Pointsbam() is the function call. When you declare the function above the code does not actually do anything until you call it to execute the code within the function. To practice take out the type var part2 and change the variable to part1 = "Treehouse". You will notice that the console.log will display "Treehouse" instead of "Team" this time. Next remove the call to the function bam right before your console.log and refresh your page and you should see the word "Team" from the console.log. This will demonstrate to you what happens when you have a function but it is not being called. Hope this helps.
