### initialize2DArray
|
|
|
|
Initializes a 2D array of given width and height and value.
|
|
|
|
Use `Array.map()` to generate h rows where each is a new array of size w initialize with value. If the value is not provided, default to `null`.
|
|
|
|
```js
|
|
const initialize2DArray = (w, h, val = null) => Array(h).fill().map(() => Array(w).fill(val));
|
|
// initializeArrayWithRange(2, 2, 0) -> [[0,0], [0,0]]
|
|
```
