How can I filter it and only get the products which have catogery featured?

CodePudding user response：

Use the array filter method.

your_array.filter(item => item['category'] === "featured");

This has nothing to do with react by the way. It's vanilla javascript.

You can use the filter method.

const items = [
  {
  "_id": "61d18b98d489dfcff325843d",
  "productName": "Cantilever chair",
  "productImg": "https://i.ibb.co/k5hNxd3/image-1168.png",
  "price": 42,
  "productCode": "Y101",
  "category": "featured",
  "review": 4,

  "Color": "White",
  },

  "price": 42,
  "productCode": "Y101",
  "category": "something",
  "review": 4,
  "totalReview": 42,

  },
]

const filteredItems = items.filter(item => item.category === 'featured');
console.log('filteredItems', filteredItems)

There are many ways to do this. Here, I have two major ways to solve this:

1. using filter:

   array.filter(data => data.category === "featured")
   

2. using find:

   array.find(data => data.category === "featured")
   

The major difference is that the Filter method will return the array object. i.e [{_uId: ...}] Whereas, Find method will return the object only. i.e {_uId:...}
