NodeJS JSON error
New to asynchronous programming here.
I am trying to get JSON data and parse it in node. However, for some reason I keep getting the error:
UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): TypeError: JSON.parse is not a function
fetch(url).then(function(res) {
return res.json();
}).then(function(json) {
jsonObj=JSON.parse(json);
console.log(json);
console.log("HELLO");
console.log(jsonObj.id);
});
JSON data when jsonObj=JSON.parse(json);

Your error indicates that you have overridden the JSON object itself - something like this;
$ node
> a='{"a":7}'
'{"a":7}'
> JSON.parse(a)
{ a: 7 }
> JSON=7
7
> JSON.parse(a)
TypeError: JSON.parse is not a function
Check that the value is JSON and JSON.parse and I am pretty sure it is not a function
