filter() method for arrays

//Using .filter() method for 2 arrays below

const randomNumbers = [375, 200, 3.14, 7, 13, 852];

//1. Arrow function to filter & return values that are less than 250
const smallNumbers = randomNumbers.filter(num => num < 250);

//2. Original long form
const smallNumbers = randomNumbers.filter(function(num){
  if (num < 250) {
    return true;
  }
})

//3. refactor the original form to:
const smallNumbers = randomNumbers.filter(function(num){
  return num < 250;
 })

console.log(smallNumbers);

const favoriteWords = ['nostalgia', 'hyperbole', 'fervent', 'esoteric', 'serene'];

const longFavoriteWords = favoriteWords.filter(word => word.length >7)

console.log(longFavoriteWords);
