Tips for iterating through a nested object in JavaScript with the forEach method

Here is my answer to the query. In this snippet, results represents a freshly initialized array. The object address nests within the user object.

response.data.forEach(user => {
          results.push({
            id: user.id,
            name: user.name,
            address: user.address.number
          })
        })

When attempting to access the address object, I encounter an issue where it returns undefined. Can someone help me understand how to properly access it?

Answer №1

Without a glimpse of the data, it's tough to give a definite answer, but based on what I see, it seems like user.address.number might not be defined in your dataset. Why would you assume it is?

On another note, your use of forEach and push could be made more efficient with map:

var results = response.data.map(user => ({
  id: user.id,
  name: user.name,
  address: user.address.number
}));
