Hello JavaScript
Welcome to your first JavaScript exercise! In this exercise, you'll learn the

Why This Matters
Every program needs to communicate. Whether it's displaying information to a
user, saving data for later, or debugging your code, understanding how to output
values and store data is fundamental to everything you'll build.
console.log() will become your best friend for understanding what your code is
doing. Variables let you give names to values so you can use them throughout
your program.Let's write your first lines of JavaScript!
