17. 01. BACKGROUND
THE
REASON
FOR GO.
What changed
everything for us.
Goals for Go
Go was designed by and for people who write—and read and
debug and maintain—large software systems.
Go's purpose is not research into programming
language design.
Go's purpose is to make its designers'
programming lives better.
ELIMINATE
SLOWNESS
ELIMINATE
CLUMSINESS
IMPROVE
EFFECTIVENESS
IMPROVE
SCALE

18. BRIAN W. KERNIGHAN
“Debugging is twice as hard as writing the code in
the first place. Therefore, if you write the code as
cleverly as possible, you are, by definition, not
smart enough to debug it.”
