This is just an HTTP response, not the actual JSON.


Simply concatenation works for me like this

Using Fetch, This defines a host of utility methods to work with the query string of a can use URLSearchParams.has() to check whether a certain parameter  So first we are calling the Fetch API and passing it the URL we defined as a constant above and since no more parameters are set this is a simple GET request. Then we get a response but the response we get is not JSON but an object with a series of methods we can use depending on what we want to do with the information, these methods include:

Create an awesome JS API interface using Fetch (in less than 50 , The Fetch API provides a JavaScript interface for accessing and The fetch() method can optionally accept a second parameter, an init object that call, add credentials: 'include' to the init object you pass to the fetch() method.
