How to parse this JSON (array)

Question

Hi I have a snippet of a json I have to parse, I made it smaller so it's easier to see.

[
  {
    "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
      }
    ]
  }
]

How would I find the "name" for both sections under "trends". According to the JSONEditor I used online it says that trends is an array, I'm not familiar with getting jsonobjects when they're an array. Help please? I know how to do it if it weren't an array but now I'm struggling. Thanks!

you can access parameters inside an array of JSON by referring to the index number of the object as mentioned below:

var sampleJson = [
  {
    "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
      }
    ]
  }
]

/* To access the first object */
sampleJson.trends[0].name

/* To access the second object */
sampleJson.trends[1].name

Also you can run a for loop through the array and accessd properties:

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