I am calculating max and min value from array of integer using JavaScript but as per my code the wrong value is coming. I am explaining my code below.
const arr = [1, 2, 3, 4, 100];
const arr1 = arr.reduce((a,i) => {
let max = a > i ? a:i;
let min = a < i ? a:i;
return {max: max, min: min};
},{})
console.log(arr1);Here I am getting both max and min value as 100. Here I need to return max and min value from array.
If you want to do it with reduce this is the answer:
const arr = [1, 2, 3, 4, 100];
const arr1 = arr.reduce((a,i) => {
let max = a.max > i ? a.max:i;
let min = a.min < i ? a.min:i;
return {max, min};
},{})
console.log(arr1);
Just use Math.max() and Math.min()
const arr = [1, 2, 3, 4, 100];
var max = Math.max(...arr);
var min = Math.min(...arr);
console.log({max, min});You could destructure min and max, check each with the actual value, adjust if necessary and return a new object with short hand properties.
As start object, you need some really large values.
const
array = [1, 2, 3, 4, 100],
minMax = array.reduce(({ min, max }, value) => {
if (min > value) min = value;
if (max < value) max = value;
return { min, max };
}, { min: Infinity, max: -Infinity });
console.log(minMax);
