React’s context API finds its usage in large application components required to share data at different nesting levels. For this tiny interview, a JavaScript array containing foods have been provided, use this array to implement a feature that enables the content of the array to be toggled using the React Context API. Implement your solution in the sandbox below: ## Want some more challenge? If you completed the original goal, why not try the following bonus exercise? - Allow more foods to be added to be added to the foods array by providing a custom controlled input component. ## Code challenge solution Verify your solution with the official solution in this [sandbox](https://app.coderpad.io/sandbox?question_id=240943). ## More resources We have made available these extra resources to improve 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?
