const animals = ['hippo', 'tiger', 'lion', 'seal', 'cheetah', 'monkey', 'salamander', 'elephant'];

const foundAnimal = animals.findIndex(a => {
  return a === 'elephant';
});
console.log(animals[foundAnimal]); // uses function's returned index to display value

const startsWithS = animals.findIndex(letter => {
  return letter[0] === 's';
});
console.log(startsWithS); // function returns index number of first TRUE element
console.log(animals[startsWithS]); // used to display that element's value

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;
}
