var = "abcd"        # => "abcd"
var[0..2] = 'ggg'   # => "ggg"
var                 # => "gggd"

It just replaces indexes 0 through 2 with the string "ggg" When you assign
it to a variable, it is easier to see.

It returned "ggg" in irb (as seen on the second line) because it was
assigned through the equal sign, and assignments through equal signs always
return whatever the input was.
