A vector type
Write a constructor Vector that represents a vector in two-dimensional
space. It takes x and y parameters (numbers), which it should save to
properties of the same name.
Give the Vector prototype two methods, plus and minus, that take another
vector as a parameter and return a new vector that has the sum
or difference of the two vectors’ (the one in this and the parameter) x
and y values.
Add a getter property length to the prototype that computes the length
of the vector—that is, the distance of the point (x, y) from the origin
(0, 0)

Please pardon me, i know say i try sha
