Check if a file exists. A fs.exists implementation that is not deprecated.
Because fs.exist and fs.existsSync are deprecated this an implementation using fs.stats and fs.statsSync for get the same result.
Also always keep in mind:
fs.exists() should not be used to check if a file exists before calling fs.open(). Doing so introduces a race condition since other processes may change the file's state between the two calls. Instead, user code should call fs.open() directly and handle the error raised if the file is non-existent.
