+/**
+ * An asynchronous helper function that wraps the standard node.js fetch API.
+ * This function calls an API url passed as the first and mandatory parameter,
+ * there is an optional payload parameter to send a json object, eg. a filter.
+ * It then calls the API and returns the response body parsed  as a json object.
+ * @example <caption>fetchJson as returning function using the await keyword</caption>
+ * const data = await fetchJson('https://api-url.com/endpoint/')
+ * @example <caption>fetchJson as oneliner using the then() structure.</caption>
+ * fetchJson('https://api-url.com/endpoint/').then((data)=>{
+ *  // use data...
+ * })
+ * @param {string} url the api endpoint to address
+ * @param {object} [payload] the payload to send to the API
+ * @returns the response from the API endpoint parsed as a json object
