# Array operations.
|
|
|
|
Let's try 5 array operations.
|
|
|
|
1. Create an array `styles` with items "Jazz" and "Blues".
|
|
2. Append "Rock-n-Roll" to the end.
|
|
3. Replace the value in the middle by "Classics". Your code for finding the middle value should work for any arrays with odd length.
|
|
4. Strip off the first value of the array and show it.
|
|
5. Prepend `Rap` and `Reggie` to the array.
|
|
|
|
The array in the process:
|
|
|
|
```js no-beautify
|
|
Jazz, Blues
|
|
Jazz, Bues, Rock-n-Roll
|
|
Jazz, Classics, Rock-n-Roll
|
|
Classics, Rock-n-Roll
|
|
Rap, Reggie, Classics, Rock-n-Roll
|
|
```
