Makes it easier to access parts of a string, such as specific characters and substrings.
Returns the character at the position treating the string as an array (where 0 is the first character).
Examples:
"hello".at(0) # => "h" "hello".at(4) # => "o" "hello".at(10) # => nil
Returns the first character of the string or the first limit characters.
Examples:
"hello".first # => "h" "hello".first(2) # => "he" "hello".first(10) # => "hello"
Returns the remaining of the string from the position treating the string as an array (where 0 is the first character).
Examples:
"hello".from(0) # => "hello" "hello".from(2) # => "llo" "hello".from(10) # => nil
Returns the last character of the string or the last limit characters.
Examples:
"hello".last # => "o" "hello".last(2) # => "lo" "hello".last(10) # => "hello"
