About the Author
Nikhil Abraham is currently the CFO of Udacity, a venture-backed
education technology startup that teaches its students how to code and that
bridges the gap between real-world skills, relevant education, and
employment. Prior to joining Udacity, he worked at Codecademy. At
Codecademy, he helped technology, finance, media, and advertising
companies teach their employees how to code. With his help, thousands of
marketing, sales, and recruiting professionals have written their first lines of
code and built functional applications. In addition to his day job, he has
lectured at the University of Chicago Law School and created a course that
teaches students how to solve legal problems using open data and software.
Prior to joining startups, Nikhil worked in a variety of fields, including
management consulting, investment banking, and law; he also founded a Y
Combinator-backed technology education startup. He received a JD and
MBA from the University of Chicago and a BA in quantitative economics
from Tufts University.
Nikhil is a recent transplant from Manhattan, New York, and now lives in
Mountain View, California. Content from Nikhil's books Coding For
Dummies and Getting a Coding Job For Dummies appears in this book.

Andrie de Vries started to use R in 2009 to analyze survey data, and he has
been continually impressed by the ability of the open-source community to
innovate and create phenomenal software. During 2009 he also started
PentaLibra, a boutique market research and statistical analysis agency. After
getting increasingly involved in the R community, he joined Revolution
Analytics to help take R to enterprise customers, helping clients to deal with
the challenges of data science and big data. To maintain equilibrium in his

The ability to read, write, and understand code has never been more
important, useful, or lucrative than it is today. Computer code has forever
changed our lives. Many people can’t even make it through the day without
interacting with something built with code. Even so, for many people, the
world of coding seems complex and inaccessible. Maybe you participated in
a tech-related business meeting and did not fully understand the conversation.
Perhaps you tried to build a web page for your family and friends, but ran
into problems displaying pictures or aligning text. Maybe you’re even
intimidated by the unrecognizable words on the covers of books about
coding, words such as HTML, CSS, JavaScript, Python, or Ruby.

If you’ve previously been in these situations, 
This book explains basic concepts so you can participate
in technical conversations and ask the right questions, and it goes even further
than Coding For Dummies by covering additional topics in data science,
machine learning, and coding careers. Don’t worry — this book assumes
you’re starting with little to no previous coding knowledge, and I haven’t
tried to cram every possible coding concept into these pages. Additionally, I
encourage you here to learn by doing and by actually creating your own
programs. Instead of a website, imagine that you want to build a house. You
could spend eight years studying to be an architect, or you could start today
by learning a little bit about foundations and framing. This book kick-starts
your coding journey today.

The importance of coding is ever-increasing. As author and technologist
Douglas Rushkoff famously said, “program or be programmed.” When
humans invented languages and then the alphabet, people learned to listen
and speak, and then read and write. In our increasingly digital world, it’s
important to learn not just how to use programs but also how to make them.
For example, observe this transition in music. For over a century, music
labels decided what songs the public could listen to and purchase. In 2005,
three coders created YouTube, which allowed anyone to release songs. Today
more songs have been uploaded to YouTube than have been released by all
the record labels combined in the past century.

Accompanying this book are examples at, whose
exercises are one of the easiest ways to learn how to code without installing
or downloading anything. The Codecademy website includes examples and
exercises from this book, along with projects and examples for additional practice.

the previous chapters, if necessary.

At some point, you will get stuck, and the code you write will not work as
intended. Do not fear! There are many resources to help you, including
support forums, others on the Internet, and me! Using Twitter, you can
send me a public message at @nikhilgabraham with the hashtag
#codingFD. Additionally, you can sign up for book updates and
