from

v4.0.2 - Show latest stable - Class: String
from(position)
public

Returns a substring from the given position to the end of the string. If the position is negative, it is counted from the end of the string.

str = "hello"
str.from(0)  #=> "hello"
str.from(3)  #=> "lo"
str.from(-2) #=> "lo"

You can mix it with to method and do fun things like:

str = "hello"
str.from(0).to(-1) #=> "hello"
str.from(1).to(-2) #=> "ell"
