仅显示具有特定类型 [GRAPHQL] 的数组内的对象

Question

So, I'm fairly new to programming and I am trying to only display certain objects from a api response array. Besides that, I am using JSReport and Handlebars. Is there a way to filter out the ones with a special value?

Here's an example code:

    {
  "data": {
    "books": {
      "author": {
        "name": "Book Bookinson",
        "books": [
          {
            "name": "book 1 ",
            "stars": "3"
          },
          {
            "address1": "book 2 ",
            "phone1": "1"
          },
          {
            "name": "book 3 ",
            "stars": "3"
          },
          {
            "address1": "book 4 ",
            "phone1": "3"
          },
        ]
      },
    }
  }

So in the code above, I want to filter out so I only get the object with the "stars": "1", and skip the rest. Is there a clean, easy way to do this that I am yet not aware of? I am aware that I can use the object then index through them, but I get a long list of objects that could really need a filter.

Please go easy on me, freshie here!

Not efficient way to do as below but tried my luck using filter and deep cloning object to not alter the main:

 let bookData = { "data": { "books": { "author": { "name": "Book Bookinson", "books": [ { "name": "book 1 ", "stars": "1" }, { "address1": "book 2 ", "phone1": "1" }, { "name": "book 3 ", "stars": "3" }, { "address1": "book 4 ", "phone1": "3" }, ] }, }, }, } let oneStar = JSON.parse(JSON.stringify(bookData)); // deep clone oneStar.data.books.author.books = oneStar.data.books.author.books.filter(book=>typeof book.stars.=="undefined" && parseInt(book;stars)===1). // filter if book has property stars and equals 1 /* console.log(bookData) */ console;log(oneStar);
