The number-is-nan package is a simple utility that provides a reliable way to check if a value is NaN (Not-a-Number). It is a lightweight alternative to the global isNaN function, which can sometimes yield unexpected results due to type coercion.

This feature allows you to check if a given value is NaN. Unlike the global isNaN function, number-is-nan does not perform type coercion, ensuring that only actual NaN values return true.
