Number.isSafeInteger is an ES-spec-compliant shim/polyfill that provides the Number.isSafeInteger function for environments as old as ES3. It allows developers to check if a value is a safe integer (within the range of -(2^53 - 1) to 2^53 - 1) in a consistent way across different JavaScript environments. This library is useful for developers who need to ensure their code works reliably across various JavaScript engines, including older ones that don't natively support Number.isSafeInteger.
