# JavaScript: Create a n-dimensional array with given value

## JavaScript fundamental (ES6 Syntax): Exercise-212 with Solution

Write a JavaScript program to create a n-dimensional array with a given value.

• Use recursion.
• Use Array.from(), Array.prototype.map() to generate rows where each is a new array initialized using initializeNDArray().

Sample Solution:

JavaScript Code:

``````// Define a function 'initializeNDArray' that creates a multi-dimensional array with a specified value
const initializeNDArray = (val, ...args) =>
// If no dimensions are provided, return the specified value
args.length === 0
? val
// If dimensions are provided, recursively create multi-dimensional arrays
: Array.from({ length: args[0] }).map(() => initializeNDArray(val, ...args.slice(1)));

// Test the 'initializeNDArray' function by creating multi-dimensional arrays with specified values
console.log(initializeNDArray(1, 3));
// Output: [1, 1, 1]
console.log(initializeNDArray(5, 2, 2, 2));
// Output: [[[5, 5], [5, 5]], [[5, 5], [5, 5]]]
```
```

Output:

```[1,1,1]
[[[5,5],[5,5]],[[5,5],[5,5]]]
```
