Creating a function which returns the highest product of three numbers

Good afternoon, I was given a task to create to a function which returns the multiply of three highest numbers in array.

The only way of how I manage to do this.

var stringArray = new Array('8','-1','2','2','0','14');

// Converting strings to numbers
var intArray = stringArray.map(Number);

// Sorting out and multiplying result
var first = intArray.sort(function(a,b){return b-a})[0]; 
var second = intArray.sort(function(a,b){return b-a})[1]; 
var third = intArray.sort(function(a,b){return b-a})[2]; 
console.log(first * second * third); // 224 is result

Any way of how I can do it in a function?

let stringArray = new Array('8','-1','2','2','0','14');

// Converting strings to numbers
let intArray = stringArray.map(Number);

const result = intArray.sort((a, b) => b - a).slice(0,3).reduce((acc,cur) =>  acc*cur);

console.log(result);

You can do it like this:

let result = stringArray.map(Number).sort((a,b)=>b-a).slice(0,3).reduce((acc,a)=> acc*a,1)
