Breaking down this JSON (array)

Greetings! I have a section of JSON data that requires parsing, and I have condensed it for better visibility.

[
  {
    "trends": [
      {
        "name": "#CyberMonday",
        "url": "https://twitter.com"
      },
      {
        "name": "#BlackFriday",
        "url": "https://twitter.com"
      }
    ],
    "as_of": "2016-11-28T20:46:09Z",
    "created_at": "2016-11-28T20:40:17Z",
    "locations": [
      {
        "name": "Worldwide",
        "woeid": 1
      }
    ]
  }
]

I am seeking guidance on how to retrieve the "name" values from both sections within the "trends" array. The online JSONEditor I utilized indicated that "trends" is an array, and I'm uncertain about accessing JSONObject elements within an array. Your assistance would be greatly appreciated as I understand how to do it with non-array objects but now find myself facing difficulty. Thank you in advance!

If you have a JSON array, you can access specific parameters by using the index number of the object like this:

var exampleJson = [
  {
    "products": [
      {
        "name": "iPhone",
        "price": "$999"
      },
      {
        "name": "iPad",
        "price": "$499"
      }
    ],
    "date_updated": "2020-12-05T10:30:21Z",
    "last_modified": "2020-12-04T15:45:13Z",
    "locations": [
      {
        "city": "New York",
        "zipcode": 10001
      }
    ]
  }
]

/* Accessing the first object */
exampleJson.products[0].name

/* Accessing the second object */
exampleJson.products[1].name

You can also iterate through the array using a for loop to access properties:

for(var i=0; i < exampleJson.products.length; i++){
    console.log(exampleJson.products[i].name);
}
