Lodash _.maxBy

Overview

The lodash _.maxBy method is a useful tool for developers working with JavaScript who need to find the maximum value from a given array of objects based on a specified property of those objects.

The syntax for using _.maxBy is as follows:

_.maxBy(array, [iteratee=_.identity])

In this syntax:

  • array is the array of objects that we want to search through.
  • iteratee is an optional parameter that specifies the property we want to search by. By default, _.identity is used, meaning that the objects will be compared by their raw values.

Here's an example snippet of code showing how to use _.maxBy to find the object with the highest value property from an array:

const objects = [{ 'n': 1 }, { 'n': 2 }];
 
_.maxBy(objects, function(o) { return o.n; });
// => { 'n': 2 }
 
// The `_.property` iteratee shorthand.
_.maxBy(objects, 'n');
// => { 'n': 2 }

In this example, the _.maxBy method is used to return the object with the highest n property from the objects array.

The _.maxBy method is particularly useful for larger arrays where it's inefficient to iterate through the entire array to find the maximum value. Instead, _.maxBy returns the object with the highest value in a single iteration, making it much more efficient.

Overall, _.maxBy is a powerful and flexible method for JavaScript developers who need to perform maximum value calculations on arrays of objects.
