Initializes and fills an array with the specified values.
|
|
|
|
Use `Array(n)` to create an array of the desired length, `fill(v)` to fill it with the desired values.
|
|
You can omit `val` to use a default value of `0`.
|
|
|
|
```js
|
|
const initializeArrayWithValues = (n, val = 0) => Array(n).fill(val);
|
|
```
|
|
|
|
```js
|
|
initializeArrayWithValues(5, 2); // [2, 2, 2, 2, 2]
|
|
``` |
