Suppose I have the following map object
const items = new Map([['item1','A'], ['item2','B'], ['item3', 'C']])
I want to fetch the key at index 2. Is there a way other than using a for loop to get the key of item at index = 2 ?
Got this working as per the answer -
Array.from(items.keys())[2]
To fetch the key at index 2, do the following:
// Your map
var items = new Map([['item1','A'], ['item2','B'], ['item3', 'C']]);
// The key at index 2
var key = Array.from(items.keys())[2]; // Returns 'item3'
// The value of the item at index 2
var val1 = items.get(key); // Returns 'C'
// ... or ...
var val2 = items.get(Array.from(items.keys())[2]); // Returns 'C'
Maps might be ordered, but they are not indexed. The only way to get the nth item is a loop.
