Blog Questions

Use the code insert tool and provide examples to answer these two questions. Use JS comment syntax to describe your example.

  • Give an example of a webpage that uses an array of objects? Provide a link. Describe a possible data structure for the object which is used over and over again. Screenshot the example and write a data structure for it using the insert code. Here’s an example:
  • var hackerNewsPosts = [
        {
            post_title: "FaunaDB 2.5.4",
            post_link: "https://jepsen.io/analyses/faunadb-2.5.4",
