javavscript get max value in array 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: get max element of array javascript

const maxMinArray = (a,b,...c) =>{
    //we are concatinating this array
    let array = [a,b];
    let newArray = array.concat(c);
    //now let's get started with the excersice
    let max = 0;
    for(let number of newArray){
        if(max<number){
            max = number;
        }
    }
    let min = max;
    for(let number of newArray){
        if(number<min){
            min = number;
        }
    }
    return console.log(max + ' ' + min)
}
//example: 
maxMinArray(12,14,15,23)
