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.
