# --description--
An *identity matrix* is a square matrix of size \\( n \\times n \\), where the diagonal elements are all `1`s (ones), and all the other elements are all `0`s (zeroes).
Uma *matriz identidade* é uma matriz quadrada de tamanho \\( n \\times n \\), onde os elementos diagonais são todos `1` (um) e todos os outros elementos são `0`(zero).

# --instructions--
Write a function that takes a number `n` as a parameter and returns the identity matrix of order \\( n \\times n \\).
Escreva uma função que recebe um número `n` como um parâmetro e retorna a matriz identidade de ordem \\( n \\times n \\).
# --hints--
`idMatrix` should be a function.
`idMatrix` deve ser uma função.
```js
assert(typeof idMatrix == 'function');
```
`idMatrix(1)` should return an array.
`idMatrix(1)` deve retornar um array.
```js
assert(Array.isArray(idMatrix(1)));
```
`idMatrix(1)` should return `[ [ 1 ] ]`.
`idMatrix(1)` deve retornar `[ [ 1 ] ]`.
```js
assert.deepEqual(idMatrix(1), results[0]);
```
`idMatrix(2)` should return `[ [ 1, 0 ], [ 0, 1 ] ]`.
`idMatrix(2)` deve retornar `[ [ 1, 0 ], [ 0, 1 ] ]`.
```js
assert.deepEqual(idMatrix(2), results[1]);
```
`idMatrix(3)` should return `[ [ 1, 0, 0 ], [ 0, 1, 0 ], [ 0, 0, 1 ] ]`.
`idMatrix(3)` deve retornar `[ [ 1, 0, 0 ], [ 0, 1, 0 ], [ 0, 0, 1 ] ]`.
```js
assert.deepEqual(idMatrix(3), results[2]);
```
`idMatrix(4)` should return `[ [ 1, 0, 0, 0 ], [ 0, 1, 0, 0 ], [ 0, 0, 1, 0 ], [ 0, 0, 0, 1 ] ]`.
`idMatrix(4)` deve retornar `[ [ 1, 0, 0, 0 ], [ 0, 1, 0, 0 ], [ 0, 0, 1, 0 ], [ 0, 0, 0, 1 ] ]`.
```js
assert.deepEqual(idMatrix(4), results[3]);
