How the web works
Type a URL from a client (e.g. google.com)
http://www.bit.ly/introjs-la
Browser sends an HTTP request asking for specific files
Browser receives those files and renders them as a website

History of Javascript
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

Javascript today
Has large community of developers, libraries and
frameworks
Lots of job opportunities
Also the syntax is easier to understand for ﬁrst-time
developers
