how to find max number in array js code example

Example 1: max value in array javascript

// For large data, it's better to use reduce. Supose arr has a large data in this case:
const arr = [1, 5, 3, 5, 2];
const max = arr.reduce((a, b) => { return Math.max(a, b) });

// For arrays with relatively few elements you can use apply: 
const max = Math.max.apply(null, arr);

// or spread operator:
const max = Math.max(...arr);

Example 2: Find the maximum number of an array js

function getMaxOfArray(numArray) {
    return Math.max.apply(null, numArray);
}

Example 3: how to find max number in array javascript

const array1 = [1, 3, 2];
console.log(Math.max(...array1));

Example 4: Find the maximum number of an array js

Math.max(10, 20);   //  20
Math.max(-10, -20); // -10
Math.max(-10, 20);  //  20

Example 5: javascript set value to the largest value in an array

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