Check if a number is prime and optimize the code.

• Start by checking if the number is less than 2, in which case it is not prime.

• Iterate from 2 to the square root of the number and check if any of them divide the number evenly.

• If a divisor is found, the number is not prime. Otherwise, it is prime.

To optimise API calls in React, use asynchronous functions and caching techniques.

• Use async/await to handle API calls

• Implement caching to reduce network requests

• Use memoization to avoid unnecessary re-renders

• Consider using a state management library like Redux

• Use performance profiling tools like React DevTools
