“Oh, boy, so you actually learned something today?” Rick Sanchez.
Functions are part of what makes JavaScript great, and are also one of the most challenging aspects to understand.
Functions can be used to prevent repetition, separate concerns, or make applications that would just be too complicated without them.
As a professional web developer, you can expect to encounter many different kinds of functions every single day, like the ones covered by this course.

“Tomorrow, and tomorrow, and tomorrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more.” Shakespeare
