00:00:00,090 --> 00:00:08,190
Javascript variables can hold many data types including numbers strings arrays and objects.

2
00:00:10,930 --> 00:00:19,210
On this slide we can see that the first variable age contains a single numerical value sixteen.

3
00:00:19,400 --> 00:00:23,530
The second variable last name stores a string.

4
00:00:23,690 --> 00:00:30,220
JOHNSON The variable cars stores multiple strings.

5
00:00:30,220 --> 00:00:37,940
This is known as an array will explore arrays in more detail later in this course.

6
00:00:38,030 --> 00:00:42,630
The last variable person is an object object.

7
00:00:42,640 --> 00:00:49,350
Variables also store multiple values but each value is relevant to an assigned property.

8
00:00:50,980 --> 00:00:59,600
For this reason each name and value in an object is referred to as a single property in this case first

9
00:00:59,600 --> 00:01:00,040
name.

10
00:01:00,080 --> 00:01:06,200
John is our first property of the object person.

11
00:01:06,200 --> 00:01:11,060
Don't worry if you find this confusing we'll work with objects later in this course.
