Recently, whilst working on a project I needed to take HTML FormData and then convert it to JSON to be sent off to an API. By default the FormData object does not work in the way you would want it to for JSON.
Using thefor..ofsyntax introduced in ECMAScript 2015, we can access the form data entries and iterate over them to get key and value pairs. This will be the verbose solution, scroll to the bottom to get the cleaner solution using.reducebelow.
