Method description:
Delete file operation.
grammar:

path file path
callback callback, passing an exception parameter err.
example:
The code copy is as follows:
var fs = require('fs');
var filepath = '126.txt';
fs.unlink(filepath, function(err){
if(err){
throw err;
}
console.log('file:'+filepath+'Delete successfully!');
})
Source code:
The code copy is as follows:
fs.unlink = function(path, callback) {
callback = makeCallback(callback);
if (!nullCheck(path, callback)) return;
binding.unlink(pathModule._makeLong(path), callback);
};
