Spread the love

To retrieve a property of a JSON object by index with JavaScript, we use the Object.values method.

For instance, we write

const obj = {
  set1: [1, 2, 3],
  set2: [4, 5, 6, 7, 8],
  set3: [9, 10, 11, 12],
};

const values = Object.values(obj);
console.log(values[1]);

to call Object.values with obj to return an array of obj property values.

Then we get the 2nd entry from values with values[1].

Conclusion

To retrieve a property of a JSON object by index with JavaScript, we use the Object.values method.
