JSON Question

In my Google Search API call, It is returning a valid JSON, but whenever I parse it to get a specific value, I get Undefined

Here is my JSON that I've collected from a simple Google Api Search
I want to get the first Url (https://www.facebook.com/Rashtriye-Goraksha-Sena-Appeal-Pls-Save-Mother-Cow-149271605156819/)
Don't ask me why thats the first link for cow pls lol

With the below code

result=JSON.parse(body);
callback(result);
console.log(result);


It will return to me a valid JSON
I get the aforementioned JSON and it all works well

Unfortunately, I dont want the JSON
... I just want the first URL

I've tried

console.log(result.items.link)
console.log(result.items.0.link)
console.log(result.items."0".link)


None of these versions work.
Is my Json parser wrong?

Answer

You want to do

result.items[0].link

result.items is an array. To access the first element of an array you must use square brackets.
