What I Wish I Knew Before I Started Coding

WHAT I WISH I KNEW BEFORE I STARTED CODINGwith Mattan Griffel, CEO of One Month

Coding Languages are HUGE

Ruby

Coding Languages are HUGE

Ruby

And you only need to know a tiny bit of them

Many experienced developers only barely scratch the surface

Many experienced developers only barely scratch the surface(A typical developer searches Google once for every 10 lines of code they write)

50% of developers are self-taught

Did you know there are 1,025,109.8 words in the English language?

…yet the average adult knows only 20,000-35,000?

C, Java, C++, PHP, JavaScript, Python, C#, Perl, SQL, Ruby, Shell, Visual Basic, Assembly, Actionscript, Where do you start? Delphi, Pascal, Scheme, Haskell, Tcl, Backbone, Fortran, Ada, Lua, ColdFusion, Cobol, Erlang, D, Scala, Smalltalk, Ocaml , Forth , Rexx , Hadoop, Node.js, Lisp, Objective C, Swift

Web applications are applications that you access over the internet

Every application has a front-end and a back-end

The front-end is what you see

Front-end languages: • HTML • CSS • JavaScript

The back-end is what you don’t see

DatabaseRules

Web Pages

The back-end is what you don’t see

Programming languages: PHP, Ruby, Python, Java

Database languages: SQL

DatabaseRules

Web Pages

They’re all the same, just different

PHP Python Ruby

echo “Hello World”; print(‘Hello World’) puts “Hello World”

Hello World Hello World Hello World

echo “Hello World”; print(‘Hello World’) puts “Hello World”

Programming languages are just languages for humans to talk to computers

Languages started off being very computer-friendly but not very human-friendly

Example in Assembly: Print “Winter is coming.”section .text global _start

_start:

mov edx,len mov ecx,msg mov ebx,1 mov eax,4 int 0x80

mov eax,1 int 0x80

section .data

msg db ‘Winter is coming.',0xa len equ $ - msg

Example in Java: Print “Winter is coming.”

public class HelloWorld { public static void main(String[] args) { System.out.println(“Winter is coming."); } }

Example in Ruby: Print “Winter is coming.”

puts “Winter is coming.”

Now there are web application frameworks

Web Pages

Now there are web application frameworks

Web application frameworks: Wordpress, Ruby on Rails, Django

DatabaseRules

Web Pages

Web application frameworks “alleviate overhead associated with web development by providing libraries for database access, templating frameworks, and session management.”

help you build web apps really quickly

~75% of coding is Googling

Stack Overflow

+ ask someone

Everyone will tell you something different

Coding in a nutshell
