ngOnInit() {
  this.booksByStoreID = this.books.filter(
          book => book.store_id === this.store.id);
}
var words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];

const result = words.filter(word => word.length > 6);

console.log(result);
const words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];

const threeLetterWords = words.filter(word => word.length <= 5)

console.log(threeLetterWords);

// RESULT: (3) ["spray", "limit", "elite"]
const myNum = [2,3,4,5,6,7,8,9,10];
//using filter gives us a new array
const divisibleBy3 = myNum.filter(eachNum => eachNum%3==0); 
console.log(divisibleBy3); //output:[3,6,9]
const items = ['a', 'b', 'c', 'd', 'e', 'f']
const valueToRemove = 'c'
const filteredItems = items.filter(item => item !== valueToRemove)
// ["a", "b", "d", "e", "f"]
const numbers = [2, 4, 5, 3, 8, 9, 11, 33, 44];
const filterNumbers = numbers.filter((number) => number > 5);
console.log(filterNumbers)
//Expected output:[ 8, 9, 11, 33, 44 ]
