Answer 1

Cesium's "Sandcastle" test environment does not include a means to include JQuery. Instead, you can use Cesium's own helper functions for things like this, such as Cesium.Resource.fetchJson.

For example: Live Sandcastle Demo

var viewer = new Cesium.Viewer("cesiumContainer");

Cesium.Resource.fetchJson({
  url: "https://reqres.in/api/unknown/2"
}).then(data => {
  console.log(JSON.stringify(data, null, '    '));
});
