Course Description
“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.
“Sometimes science is more art than science.” – Rick Sanchez
In this course, you'll learn the following:
How to use functions and what they are
How to define functions and several different ways
How to call functions as many times as you need

Composing functions with currying and factories
Using the this keyword
Using callback functions
And much more!

Instructor Details
Daniel Stern
Known in development circles as “the Code Whisperer," Daniel Stern has been believed to possess a supernatural connection to computers ever since he talked the supercomputer Deep Blue off the roof of a twelve-story St. Petersburg apartment building, following its shameful loss to Gary Kasparov.
He can often be found singing softly to his tablet, or gently caressing his aluminum keyboard in his arms.
Daniel has been working as a front end and full stack developer in the tech industry since 2011. He's developed single-page applications for banks like CIBC, charities like the Ontario Institute for Cancer Research, and at ad agencies like McLaren McCann, TraffikGroup and Olson. Throughout his labors, he's worked on computer programming in his spare time because, well, he's obsessed with it.
In addition to being featured in both CSS Weekly and JavaScript weekly, Daniel is well-known throughout the open-source community for maintaining several open-source tools, most notably the Angular.js and LESS-based tool, Range .css and the Angular .js audio tool, ngAudio.
In addition to being trusted by the open source community to develop top-quality, functional code, Daniel has also been invited to speak at numerous conferences including Full Stack Conference 2014 in London, England.
Daniel is an active learner and very passionate about the following technologies,
- Node.js
- Angular.js
- TypeScript
- MongoDB
- LESS
- Grunt
- Yeoman
- Many, many, many more
