- 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 5
- 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. 6
- 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. 7
- 8. How to pick a first language? Objective Popularity Accessibility Job prospects Longevity 8
- 9. Potential objectives Frontend Backend Full-stack Data & Analytics 9
- 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 10
- 11. Data/Analytics Data & Databases Database Engineers, Data Scientists, Data Analysts 11
- 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 12

- 14. Javascript 14
- 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. 17
- 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 21
- 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! 27
