How to get value at a specific index of array In JavaScript?

Just use indexer

var valueAtIndex1 = myValues[1];

Update from Chrome 92 (released on: July 2021)

You can use at method from Array.prototype as follows:

var valueAtIndex1 = myValues.at(1);

See more details at MDN documentation.

You can just use []:

var valueAtIndex1 = myValues[1];

Array indexes in JavaScript start at zero for the first item, so try this:

var firstArrayItem = myValues[0]

Of course, if you actually want the second item in the array at index 1, then it's myValues[1].

See Accessing array elements for more info.

indexer (array[index]) is the most frequent use. An alternative is at array method:

const cart = ['apple', 'banana', 'pear'];
cart.at(0) // 'apple'
cart.at(2) // 'pear'

If you come from another programming language, maybe it looks more familiar.
