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

I have an array and simply want to get the element at index 1.

var myValues = new Array();
var valueAtIndex1 = myValues.getValue(1); // (something like this)

How can I get the value at the 1st index of my array in JavaScript?


Just use indexer

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.


You can just use []:

var valueAtIndex1 = myValues[1];

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.
