One might wonder how we can find out the names of the fields of a structure at execution time. In such cases, we need to use reflection. Apart from enabling us to print the fields and the values of a defined structure, reflection also allows us to explore and manipulate structures like the ones created from decoding JSON data, where the fields and their types are not known beforehand.
