Question

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?

Answer 1

You can access an element at a specific index using the bracket notation accessor.

var valueAtIndex1 = myValues[1];

On newer browsers/JavaScript engines (see browser compatibility here), you can also use the .at() method on arrays.

var valueAtIndex1 = myValues.at(1);

On positive indexes, both methods work the same (the first one being more common). Array.prototype.at() however allows you to access elements starting from the end of the array by passing a negative number. Passing -1 will give the last element of the array, passing -2 the second last, etc.

See more details at the MDN documentation.
