This document discusses how to choose a first programming language. It recommends JavaScript for frontend, JavaScript or Python for backend, and JavaScript for full-stack development. Python is recommended for data and analytics. The document provides a brief history and overview of JavaScript and Python, explaining why they are good first languages due to their popularity, accessibility, and job prospects. It also gives examples of basic variables and functions in each language.

4. What is programming?
Programming is:
writing instructions for a computer to execute

5. Learning how to code
Learning to code is a process of learning how to solve
problems in a structured way and then translate those
solutions into instructions a computer can understand and
implement.
Variables, loops, arrays, functions exist in all languages —
stick to one until you understand the core concepts

6. Pick one thing and master it.
Don’t jump around. It will be surprisingly easy to pick up more
languages once you understand the fundamentals.

7. Does the first language you choose matter?
It matters, but not in the way most people think. You should
pick the language that makes it easiest for you to learn how
to code.

10. Front end, Back end, and Full stack
Client (sends requests)
Frontend Developer
Manages what user sees
Server (sends response)
Backend Developer
Manages what app does

11. Data/Analytics
Data & Databases
Database Engineers,
Data Scientists,
Data Analysts

12. Benefits of Popularity & Accessibility
Has large community of developers, libraries and
frameworks => easier to learn & debug
Syntax is less complicated and more intuitive for first-time
developers
Helps you focus on learning how to code rather than get
distracted by the nuances of the language

13. Our recommendations
Frontend: Javascript
Backend: Javascript/Python
Full-stack: Javascript
Analytics: Python

14. Javascript

15. Javascript history
Written by Brendan Eich in 1995 for Netscape
Initial version written in 10 days
Completely unrelated to Java, but maybe named after it to
draft off its popularity
Over 10 years, became default programming language for
browsers
Continues to evolve under guidance of ECMA
International, with input from top tech companies
15

16. Javascript
16

17. Why Javascript?
94% of all websites in the world use Javascript.
Javascript has a monopoly on front end web
development.
All browsers already have Javascript interpreters
included.
Node.js allows Javascript to be written on the
back end as well.
Knowing Javascript means you can create full
stack web applications in minutes.

18. Python
18

19. Python history
First release in 1991
Designed to be simpler and more readable
Named after “Monty Python’s Flying Circus”
19

20. Python today
Since 2003, consistently ranked in top 10 most
popular languages.
As of 2017, was fifth most popular language,
currently #3 on Github
Has become standard language in computer
science curriculums (displacing Java)
20

21. Python today

22. Python analytics
Data scientists are increasingly using Python
over R
Python has excellent modules for “big data”
analysis and machine learning (NumPy, Pandas,
sklearn)
22

23. Javascript basics: variables
var cars = 20
Initialize variable
Name of variable
Value of variable
23

24. Python basics: variables
cars = 20
Name of variable
Value of variable
24

25. Javascript basics: functions
function greet() {
return "Hello world!";
}
Initialize function Name of function
What the function does
25

26. Python basics: functions
def printme():
print "Hello world!"
return
Initialize function Name of function
What the function does
26

27. That's it!
Understanding variables and functions means
you already understand the fundamentals of a
programming language!

28. How can I learn?
Build stuff + Google
Free online resources (e.g. CodeAcademy)
Flexible coding bootcamps (e.g Thinkful)
Full-time coding bootcamps (e.g. GA)
Full degree programs (Georgia Tech)
