The first element of an array is at position zero. So, if you want to access the first element of an array, you can do it like so:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var arr = ["Programming", 123, "Coding", 789];
|
||
|
|
|
||
|
|
var firstElem = arr[0] // This is "Programming"
|
||
|
|
var thirdElem = arr[2] // This is "Coding"
|
||
|
|
var fourthElem = arr[3] // This is 789
|
||
|
|
```
|
||
|
|
|
||
|
|
Notice that the length of the array is 4, and the position of the last element of the array is 3.
