03. LETTER TREE


# LINE BY LINE

JavaScript is run one line at a time, from top to bottom of the file.

We can output multiple messages by using multiple console.log() methods. For
example, if we want to print out two simple greetings:

console.log("🚌 Greyhound to New York");
console.log("🕥 Departs at 9:30 am");



This is will output:

🚌 Greyhound to New York
🕥 Departs at 9:30 am



Now let's use what we just learned to complete a special challenge!


# INSTRUCTIONS

Suppose we want the output to look exactly like this pattern below:

   a
  b c
 d e f
g h i j
   k



How can you do that?

Create a JavaScript program that prints this pattern exactly as shown.

This will likely take some trial and error, but give it a shot!
