Ranges constructed using .. run from the start to the end inclusively.

Those created using exclude the end value. When used as an iterator, ranges return each value in the sequence.

A range (1..5) means it includes 1, 2, 3, 4, 5 values and a range (1...5) means it includes 2, 3, 4 values

The simplest string literals are enclosed in single quotes (the apostrophe character).

The text within the quote marks is the value of the string:

'This is a simple Ruby string literal'
