## Create complex multi-dimensional arrays
|
||
|
|
|
||
|
|
- The first string - `deep` - must be inserted three levels deep. This means within exactly threes sets of `[square-brackets]`.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
let threeLevelArray = ["first level", ["Two levels deep", ["Three levels deep"]]];
|
||
|
|
```
|
||
|
|
- Using this logic insert strings `deep` , `deeper` and `deepest` in the matrix three levels deep, four levels deep and five levels deep respectively.
|
||
|
|
|
||
|
|
## Solution:
|
||
|
|
```javascript
|
||
|
|
let myNestedArray = [
|
||
|
|

|
||
|
|
['unshift', false, 1, 2, 3, 'complex', 'nested'],
|
||
|
|
['loop', 'shift', 6, 7, 1000, 'method'],
|
||
|
|
['concat', false, true, 'spread', 'array',["deep"]],
|
||
|
|
['mutate', 1327.98, 'splice', 'slice', 'push', [["deeper"]]],
|
||
|
|
['iterate', 1.3849, 7, '8.4876', 'arbitrary', 'depth', [[["deepest"]]] ]
|
||
|
|
// change code above this line
|
||
|
|
];
|
||
|
|
```
