Objects can also contain functions, which are called methods.

To change the value of a property on an existing JS object, you can use a very similar option as when you access the value. Or you can use the bracket notation with the name of the property inside a string within square brackets - objectName as in the example below: EXAMPLE You can use the dot notation with the name of the property after the period - objectName.propertyName as in the example below: EXAMPLE There are two ways to access the value of an object property. You must also use the opening and closing curly brackets when defining your objects. The name:value pairs don’t have to be on different lines for the code to work, but it is much easier to read and understand the code by formatting it that way. JavaScript object values are written in the format of name:value and the different pairs are separated by commas. Here’s how we would turn this into an object in JavaScript: EXAMPLE The course name is “GRA 2032”, it starts at 8:00am and it ends at 10:00am. This time let’s think about a course you have to take. Objects use keys to name values, much like how is done with variables. The values within a JS object are known as properties.

JavaScript objects are variables that contain multiple data values. A red Ford Focus and a blue Honda Civic are both “cars”, but they are different makes, models, and colors.

Every car has these properties, but the values are different from one car to another. Cars come in all shapes and sizes - different colors, different makes and models, different weight, etc. JavaScript objects are best explained by thinking of a real-world object.
