Tips on iterating through fields within an Express request to construct form data?

I am currently working with a piece of code which contains the following:

res.send(`
        fd.append('policy', '${presigned.fields.Policy}');
        fd.append('X-Amz-Signature', "${presigned.fields['X-Amz-Signature']}");
        fd.append('X-Amz-Credential', "${presigned.fields['X-Amz-Credential']}");
        fd.append('X-Amz-Algorithm', "${presigned.fields['X-Amz-Algorithm']}");
        fd.append('X-Amz-Date', "${presigned.fields['X-Amz-Date']}");
        fd.append('X-Amz-Security-Token', "${presigned.fields['X-Amz-Security-Token']}")
`)

My challenge lies in dynamically iterating through the presigned.fields, as some may be present or missing depending on the context. I need to find a way to generate client-side JavaScript that can handle this variability. Any suggestions on how others have approached this problem?

Ensuring security measures, it's advisable to verify parameters on the server side and conduct thorough checks for potential SQL injection vulnerabilities when handling database inputs.

var _data = {
 username: 'john',
 password: '12345'
};

for (var _property in _data) {
  var _value = _data[_property];

  if (_property === 'username') {
    //perform validation for username
    console.log(_value);
  }

  if (_property === 'password') {
    //implement password validation procedures
    console.log(_value);
  }
}
