To find the maximum y value of the objects in array:
Math.max.apply(Math, array.map(function(o) { return o.y; }))
or in more modern JavaScript:
Math.max(...array.map(o => o.y))
Warning:
This method is not advisable, it is better to use reduce. With a large array, Math.max will be called with a large number of arguments, which can cause stack overflow.

Find the object whose property "Y" has the greatest value in an array of objects
One way would be to use Array reduce..
const max = data.reduce(function(prev, current) {
return (prev && prev.y > current.y) ? prev : current
}) //returns object
- https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce
- http://caniuse.com/#search=reduce (IE9 and above)
If you don't need to support IE (only Edge), or can use a pre-compiler such as Babel you could use the more terse syntax.
const max = data.reduce((prev, current) => (prev && prev.y > current.y) ? prev : current)
Note that if you have multiple objects sharing the same max value, it will only return the first matched object.

How to find the max id in an array of objects in JavaScript
March 14, 2019 - If you dig into Math.max you will find out that it can take a list of numbers or an array of numbers. This means that all you have to do is get an array of id's and you can pass that into the max() function. If you were paying attention you ...
ES6 Find the maximum number of an array of objects?
If you want to use ES6 and get this done in one line:
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);
Can replace the ternary with a Math.max(acc, shot.amount), along with many other multiple methods. The issue with the reduce function you produced on SO, your reducer accumulator/initial value (0) was placed in the wrong spot.

February 14, 2018Map or Reduce to calculate max value from JSON
That SO solution is more elegant. It uses map to create a new array of just the values, then passes that to the built-in Math.max. Your solution is slightly more complicated and basically does just what Math.max does anyway. Edit: However, I knocked together a quick jsperf and it looks like the Math.max version is slower: http://jsperf.com/math-max-vs-ternery Personally I'd still go with Math.max as I find it easier to understand, and I really doubt there will be many situations in which this'd be a performance bottleneck.

How to get the element with the max value in a JavaScript array · Sean Connolly
One notable trait of this array is that it is unsorted so we cannot simply grab the first element (or last, depending on sort direction). Instead we need an algorithm that compares the elements against each other and returns the element with the max wins value. The Array.reduce is our friend here. If you haven't seen the function signature before, it reads a bit awkwardly: arr.reduce(callback( accumulator, currentValue[, index[, array]] ) { // return result from executing something for accumulator or currentValue }[, initialValue]);

console.log(Math.max(1, 3, 2)); // Expected output: 3 console.log(Math.max(-1, -3, -2)); // Expected output: -1 const array = [1, 3, 2]; console.log(Math.max(...array)); // Expected output: 3 ... Zero or more numbers among which the largest value will be selected and returned. The largest of the given numbers. Returns NaN if any of the parameters is or is converted into NaN. Returns -Infinity if no parameters are provided. Because max() is a static method of Math, you always use it as Math.max(), rather than as a method of a Math object you created (Math is not a constructor).

July 18, 2023 - const max = array.reduce((prev, current) => (prev.attribute > current.attribute) ? prev : current); Here, the reduce() method allows us to iterate through an array and apply a reduction operation. In this case, we use reduce() to compare the attribute value of each object with the previous maximum value and return the object with the higher attribute value.
