Description

In this lab, you will be working with JavaScript objects. An object is a collection of properties, and a property is an association between a name and a value. Also known as key-value pairs. Object properties are unordered. Object values are accessed through the corresponding property name. Objects in JavaScript can be compared to real-world items such as cars or a user.

In this lab, you will declare an object and use both dot notation and square bracket notation to access, add, and change property values. Each check will ask you to output data to the console.

  • Declare a JavaScript Object
  • Access the value of an object property
  • Add to and replace property values of an object
