//.map takes an argument of a callback function and returns a new array

const animals = ['Hen', 'elephant', 'llama', 'leopard', 'ostrich', 'Whale', 'octopus', 'rabbit', 'lion', 'dog'];

// Create the secretMessage array below
const secretMessage = animals.map(animals =>{
return animals[0];
});

console.log(secretMessage.join(''));
//output 'HelloWorld'
const bigNumbers = [100, 200, 300, 400, 500];

// Create the smallNumbers array below
const smallNumbers = bigNumbers.map(bigNumbers =>{
  return bigNumbers / 100;
});

console.log(smallNumbers)
//output [ 1, 2, 3, 4, 5 ]

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;
}
