Page Summary
-
The
subtractmethod performs element-wise subtraction between two values. -
It takes two Array inputs, a left-hand value (
this) and a right-hand value (right). -
The method returns a new Array containing the results of the subtraction.
-
The
subtractmethod can handle both scalar and array subtraction. -
The examples demonstrate subtraction with single-element arrays, multi-element arrays, and empty arrays.
