Explain the useEffect() Hook The useEffect Hook allows you to perform side effects in your components like data fetching, direct DOM updates, timers like setTimeout(), and much more. This hook accepts two arguments: the callback and the dependencies, which allow you to control when the side effect is executed. Note: The second argument is optional

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
