@ -6,11 +6,13 @@ Use recursion.
Use `Array.map()` to generate rows where each is a new array initialized using `initializeNDArray`.
```js
const initializeNDArray = (val, ...args)=>
args.length === 0 ? val : Array.from({ length: args[0] }).map(() => initializeNDArray(val, ...args.slice(1)));
const initializeNDArray = (val, ...args) =>
args.length === 0
? val
: Array.from({ length: args[0] }).map(() => initializeNDArray(val, ...args.slice(1)));
```
```js
initializeNDArray(1,3); // [1,1,1]
initializeNDArray(5,2,2,2); // [[[5,5],[5,5]],[[5,5],[5,5]]]
initializeNDArray(1, 3); // [1,1,1]
initializeNDArray(5, 2, 2, 2); // [[[5,5],[5,5]],[[5,5],[5,5]]]
