Use max method form Math class=>
Math.max(...Resul)

(if you don't know about three dots, heres the explanation)
Math.max() takes as many arguments as you need, but you don't pass the array directly, you should spread it.
Wrong: Math.max([1,2,3])
Right: Math.max(1,2,3)
That is why you use three dots to spread the array into their own elements, Math.max(...Resul)

let maxNum = Math.max(...array)
// just find the index of the maximum number in that array using findIndex.
let maxIndex = array.findIndex(num => num === maxNum)
If you wanna do it the whole process manually:
let maxAns = {
value: null,
index: null
}
/* making an answer object that contains index and value of the highest number, initially null. */
array.forEach((num, index) => {
/* Checking if the number in the loop is greater than maxAns.value, or if maxAns.value is null, if it is true, set the current num and index in maxAns */
if(num > maxAns.value || maxAns.value === null) {
maxAns.value = num
maxAns.index = index
}
})
/* Looping through array, you can also use the for(let i = 0....) loop */
console.log(maxAns)
If u didnt understand any line, ask.

maf in how I show the max number with their position in the array (if the max numbers is 50 in his position inside the array for example is 5
