--description--

Compute the Root Mean Square (RMS) of the numbers 1 through 10 inclusive.

The <abbr title="Root mean square">RMS</abbr> is calculated by taking the square root of the mean of the squares of the numbers, given by the equation:

$$x_{\mathrm{rms}} = \sqrt {{{x_1}^2 + {x_2}^2 + \cdots + {x_n}^2} \over n}. $$

--hints--

rms should be a function.

assert(typeof rms === 'function');

rms([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]) should equal 6.2048368229954285.

const arr1 = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
const answer1 = 6.2048368229954285;
assert.equal(rms(arr1), answer1);

--seed--

function rms(arr) {

}

--solutions--

function rms(arr) {
  const sumOfSquares = arr.reduce((s, x) => s + x * x, 0);
  return Math.sqrt(sumOfSquares / arr.length);
