To get max and min value from array in JavaScript, we the Math.max and Math.min methods.
For instance, we write
const array = [1, 3, 2];
const max = Math.max(...array);
const min = Math.min(...array);
to call Math.max with the array entries as arguments to return the max value from array.
And we call Math.min with the array entries as arguments to return the min value from array.
The spread operator spreads the array entries as arguments.
