Here's a fun comparison between STRIP, SQUEEZE, SQUISH with an example:

Consider a string:

name = " Rushi   Patel "

STRIP:

name.strip
Output: "Rushi   Patel"

Removes the spaces from the START and END of a string

SQUEEZE:

name.squeeze
Output: " Rushi Patel "

Literally squeezes the string, i.e squishes down any INTERNAL repeating whitespace to a SINGLE space.

SQUISH:

name.squish
Output: "Rushi Patel"

Squish does both strip and squeeze. It's not directly available in Ruby, but it's made available in Rails. It's very useful.
