Javascript - 从一个数组中获取 object，其数组与另一个数组匹配

Question

I have an array of objects ( zoo ) inside of which are some objects, and the objects have an array of objects ( animals ) in them. I need to filter the array, and get the objects with the same animal names, as another dynamic array in my code.

zoo

  0:[...]
  1:[...]
  2:
    name:"whatevername"
    city:"whatevercity"
    animals:Array(2)
        0:
          name:"somename"
          species:"somespecies"
        1: ...
    etc:"whasover"

So if my dynamic array contains somename in it, I should get the object with index 2. How do I go about something like that?

This is the function you need:

const search = keyword => zoos.find(({ animals }) => animals.some(({ name }) => name == keyword));

Here's a live example:

 const zoos = [ { name: 'Antarctic Zoo', city: 'Chilean Villa Las Estrellas', animals: [{ name: 'Chinstrap penguin', species: 'Pygoscelis antarctica' }], }, { name: 'African Zoo', city: 'Cairo', animals: [{ name: 'Lion', species: 'Panthera leo' }], } ]; const search = keyword => zoos.find(({ animals }) => animals.some(({ name }) => name == keyword)); const result = search('Lion'); console.log(result); // { name: 'African Zoo', city: 'Cairo', animals: [ { name: 'Lion', species: 'Panthera leo' } ] }
