* In this short assessment, the following code tries to implement the React Suspense API, | |
* but does so incorrectly. There are 3 core issues with how these components utilize Suspense and concurrent mode -- can you find them? | |
* | |
* In your submission, be sure to: | |
* 1) Clearly identify what the 3 core issues are, and how they violate the principles of React Suspense; | |
* 2) Write and submit the code to fix the core issues you have identified in a gist of your own | |
* | |
* If you aren't familiar with Suspense, the docs are a good starting place: | |
