noGlobalIsFinite
Diagnostic Category: lint/suspicious/noGlobalIsFinite
Since: v1.0.0
Use Number.isFinite instead of global isFinite.
Number.isFinite() and isFinite() do not have the same behavior.
When the argument to isFinite() is not a number, the value is first coerced to a number.
Number.isFinite() does not perform this coercion.
Therefore, it is a more reliable way to test whether a number is finite.
