// Iterators: .some() Method

// The some() method tests whether at least one element in the array passes the test implemented by the provided function. It returns true if, in the array, it finds an element for which the provided function returns true; otherwise it returns false. It doesn't modify the array.

const words = ['unique', 'uncanny', 'pique', 'oxymoron', 'guise'];

// Check if some els are less than 6 chars long
console.log(words.some((word) => {
  return word.length < 6;
})); // true

// Use filter to create a new array
const interestingWords = words.filter(word => {
  return word.length > 5;
});
console.log(interestingWords); // ['unique', 'uncanny', 'oxymoron']


// The every() method tests whether all elements in the array pass the test implemented by the provided function. It returns a Boolean value.

console.log(interestingWords.every((word) => {
  return word.length > 5;
} )); // true
