Get key value from an object while looping

I am lost on getting the value of height from this object for each person:

[object Object]
Adam: [object Object]
height: 192,
weight: 101
,
Grant: [object Object]
height: 171,
weight: 79




I just keep getting undefined or printing out the name.

const personData = data
Object.keys(personData).forEach((person, index) =>
console.log(person)
)


The above will just console log the name, person[0] gives me the first letter of each name and my other attempts produce undefined.

person[0]

How do I navigate to the correct value and key?

This is happening because you're iterating over the root of the object. The height, weight etc details live in sub-objects at a deeper level.

You're going to need to iterate over the object's values, not its keys, then reach in a little deeper to extrac the height property:

height

Object.values(personData).forEach((person, index) =>
console.log('Height = '+person.height);
//if you need to access the person name too...
console.log('Person = '+Object.keys(personData)[index]);
)


You are iterating over the keys of the object. In this case "Adam" and "Grant". What you want to do is to use these keys to access the object - and that is your person:

const personData = data
Object.keys(personData).forEach((name, index) =>
console.log(personData[name])
)
