filter < Array < JavaScript

The filter() method of an array filters elements to just those that pass the test in the provided function.

    
    const words = ['bugs', 'ants', 'potatoes', 'tomatoes'];

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

    console.log(filter);
    // ['potatoes', 'tomatoes']


    // common, more-advanced example
    const places = [
      {city: "Detroit", state: "Michigan"},
      {city: "Miami", state: "Florida"},
      {city: "Boston", state: "Massachusetts"},
      {city: "New York", state: "New York"}
    ];

    const placesFilterMichigan =  places.filter(places =>
      places.state == "Michigan"
    );

    console.log(placesFilterMichigan);
    [ {city: "Detroit", state: "Michigan"} ]
