How to get element of JavaScript object with an index?

To get element of JavaScript object with an index, we use the Object.keys method to get an array of keys from the object and sort it.

For instance, we write

const myObj = { A: ["Abe"], B: ["Bob"] };
const sortedKeys = Object.keys(myObj).sort();
const first = myObj[sortedKeys[0]];

to get the keys in myObj as an array of strings with Object.keys.

Then we call sort to sort the key strings in alphabetical order.

Next, we get the first key in sortedKeys with sortedKeys[0].

And then we get the value of the property with myObj[sortedKeys[0]].

Conclusion

To get element of JavaScript object with an index, we use the Object.keys method to get an array of keys from the object and sort it.
