Settings View Source Credo.Check.Warning.OperationOnSameValues (Credo v1.7.0)

This check has a base priority of high and works with any version of Elixir.

explanation

Explanation

Operations on the same values always yield the same result and therefore make little sense in production code.

Examples:

x == x  # always returns true
x <= x  # always returns true
x >= x  # always returns true
x != x  # always returns false
x > x   # always returns false
y / y   # always returns 1
y - y   # always returns 0

In practice they are likely the result of a debugging session or were made by mistake.
