Script Preparation code:

var numbers = Array.from(Array(10000), (_,x) => (Math.random()*x));

Tests:

Math.sqrt
const sum = numbers.map(number => Math.sqrt(number)).reduce((a, b) => a + b, 0) console.log(sum)
sqrt with Math.pow
const sum = numbers.map(number => Math.pow(number, 0.5)).reduce((a, b) => a + b, 0) console.log(sum)
sqrt with ** 0.5
const sum = numbers.map(number => number ** 0.5).reduce((a, b) => a + b, 0) console.log(sum)
