fs.exists, fs.existsSync - why are they deprecated?

Question

I noticed that the official node documentation says something startling about fs.exists:

\"fs.exists() is an anachronism and exists only

Answer 1

I was searching for a solution to this issue and found that fs.exists and fs.existsSync was deprecated. This seems to work well in my senario

fs.readFile(filename, 'utf8', function(err,data){
    // the err variable substitutes for the fs.exists callback function variable
    if (!err){
        // do what you planned with the file
        console.log(data)
    }else{
        // handle the non-existence of the file
        console.log('File does not exist!');
    }
});
