This PR closes issue #375 .

Earlier I had raised a PR #386 which did not work as intended. Because it had missing "response" as a dependency in the useEffect call.

The issue that needed to solve was, as during the initial render response is an empty object. based on the empty object the
tasks state was getting updated and as "response" was a dependency it kept on going in a loop.

To solve the issue. I added two checks.

  1. to only call the API when the response is an empty object.
  2. to only update the tasks state when response is not an empty object. meaning we have valid response from the API. (If this check was not added tasks would have been updated by empty object which might have caused more bugs).

To avoid the blinking effect of no tasks found. I had to add checks to see if the response is empty and if the tasks is empty. Only then we can say No tasks found.

Please find the video attached to simulate the working. In the first instance I have used a different url to get the tasks and updated my code accordingly. In the second instance I have used the /self API which for my user returns an empty array.

I checked the code, this response object holds the tasks array right? so, if yes then why are we even checking the state (task state), why not a simple check of response.length > 0 ? {render tasks} : no tasks, do check if you can do this.

if (JSON.stringify(response) === "{}") callAPI();

instead of 2 if's could we not add an if else block.
