const handleCount = () => {

console.log(count);
setCount(count + 1);
setCount(count + 1);
}

What is the difference between a hook and a utility function?

Write code to count the frequency of words in an array using both a loop and the reduce method in JavaScript.

const arr = ["apple", "mango", "seed", "apple", "protein"];

Is it a good idea to use both the Context API and Redux in a web app?

• What is the reduce function? (Learn)
• What is a polyfill?
• Write a polyfill for the reduce function.
• What is debouncing? Write a custom hook for debouncing.
• When would you prefer to use the Context API, and where would you prefer to use Redux for state management? Explain why.
