javascript get max value from array of objects code example

Example 1: javascript array find highest value of array of objects by key

Math.max.apply(Math, array.map(function(o) { return o.y; }))

Example 2: How to find the max id in an array of objects in JavaScript

const shots = [
  {id: 1, amount: 2},
  {id: 2, amount: 4},
  {id: 3, amount: 52},
  {id: 4, amount: 36},
  {id: 5, amount: 13},
  {id: 6, amount: 33}
];

shots.reduce((acc, shot) => acc = acc > shot.amount ? acc : shot.amount, 0);

Example 3: filter biggest value javascript object

const max = data.reduce((prev, current) => (prev.y > current.y) ? prev : current)

Example 4: javascript largest number in array

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

Example 5: find highest number in array javascript

function findHighestNumber(nums) {
	
	let inputs = nums.filter((val, i) => nums.indexOf(val) === i)
	let max = Math.max(...nums);
	let min = Math.min(...nums);
  
   return max + (-min);
}

console.log(difference([1, 7, 18, -1, -2, 9]));

Example 6: get object with max value javascript

let objects = [{id: 0, votes: 5}, {id: 1, votes: 3}, {id: 2, votes: 11}]

let maxObj = objects.reduce((max, obj) => (max.votes > obj.votes) ? max : obj);

/* `max` is always the object with the highest value so far. 
 * If `obj` has a higher value than `max`, then it becomes `max` on the next iteration.
 * So here:
 *  |  max = {id: 0, votes: 5},   obj = {id: 1, votes: 3}
 *  |  max = {id: 0, votes: 5},   obj = {id: 2, votes: 11}
 * reduced = {id: 2, votes: 11}
