Script Preparation code:

var N = 10000;
var xs = Array.from(Array(N).keys())
var ys = xs.map((x) => (x + 3) * 0.89 - 16)

function normalFunction(a, b) {
    return Math.sqrt(a ** 2 + b ** 2)
}

var arrowFunction = (a, b) => Math.sqrt(a ** 2 + b ** 2);

Tests:

No function
var res = new Array(N) for (let i = 0; i < N; i++) { res[i] = Math.sqrt(xs[i]**2 + ys[i]**2) }
With normal function
var res = new Array(N) for (let i = 0; i < N; i++) { res[i] = normalFunction(xs[i], ys[i]) }
With arrow function
var res = new Array(N) for (let i = 0; i < N; i++) { res[i] = arrowFunction(xs[i], ys[i]) }
