javascript set value to the largest value in an array

const max = arr => Math.max(...arr);

const array1 = [1, 3, 2];

Math.max(...array1);
// expected output: 3

//get min/max value of arrays
function getArrayMax(array){
   return Math.max.apply(null, array);
}
function getArrayMin(array){
   return Math.min.apply(null, array);
}
var ages=[11, 54, 32, 92];
var maxAge=getArrayMax(ages); //92
var minAge=getArrayMin(ages); //11

//get min/max value of arrays
function getArrayMax(array){
   return Math.max.apply(null, array);
