Front End Web Development Techdegree Student 9,937 PointsFoggy about "property" and "keys".
Objects are also great. 0:06 They provide a way to structure data that's easy to read and 0:10 retrieve using a property name or a key.
So you van retrieve data with a property, or key. Are property and keys the same, or are they different methods to retrieve data?

Property is the part of object named "name" with value 5. Key is the word "name". Specifically property refers to the key-value relationship of an object.
Here's an official property defintion from the MDN docs: https://developer.mozilla.org/en-US/docs/Glossary/property/JavaScript
