11. 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
