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

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.

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

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
Pass: None

Javascript
Pass: None

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.
