[javascript] 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?

You can use [];

var indexValue = Index[1];

shift can be used in places where you want to get the first element (index=0) of an array and chain with other array methods.

example:

const comps = [{}, {}, {}]
const specComp = comps
                  .map(fn1)
                  .filter(fn2)
                  .shift()

Remember shift mutates the array, which is very different from accessing via an indexer.

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];
