Example 3: java

An incredible language that receives far more hate than it deserves
because of it's poor beginnings.
	Everyone remembers the slow java applets but often fail to understand
Java's many positives including:
 - compatability with many different systems
 - Just-In-Time compilation making it almost as fast as a native language
 - the wide range of high-quality and open source libraries developed over
   many years

	Sure, it may not look as sexy as Python or NodeJS, but when you're
debugging the call stack 50 functions deep, you'll be glad you picked Java
