let formData: FormData = new FormData()
   formData.append('key','value')
   console.log(formData)

Result:

FormData { }

Answer 1

FormDatais not a simple js object, API link: https://developer.mozilla.org/en/docs/Web/API/FormData

let data = new FormData();
data.append('key', 'value');
console.log(data.get('key'))
