For this code challenge, a mini image gallery has been built to display images from UnSplash. Your task will be to: - consume the Unsplash API and display the images gotten from the server on the UI. - implement the loading placeholders when consuming the API so as to provide feedback. Implement your solution in the sandbox below: ## Code challenge solution Verify your solution with the official solution in this [sandbox](https://app.coderpad.io/sandbox?question_id=241231). ## More resources We have made available these extra resources to sharpen your React coding skills: - [25+ React interview questions](https://coderpad.io/interview-questions/react-interview-questions/) - [Online coding test questions for React](https://coderpad.io/online-coding-tests/react/) ## Want to conduct interviews on this platform?
