Lodash _.maxBy() method is used to compute the maximum value from the original array by iterating over each element in the array using the Iteratee function. It is almost the same as the _.max() function.
Syntax:
_.maxBy( array, [iteratee = _.identity] );
Parameters:
- array: It is the array that the method iterates over to get the maximum element.
- iteratee: It is the function that is invoked for every element in the array.
Return Value:
This method returns the maximum element.
Example 1: In this example, we are printing the maximum value of ‘n’ by the use of the _.maxBy() method.
Javascript
// Requiring the lodash library const _ = require("lodash");Â
// Original array let arr = [{ 'n': 4 }, { 'n': 2 }, { 'n': 6 }];Â
// Use of _.maxBy() method let max_obj = _.maxBy(arr, function (o) { return o.n; });Â
// Printing the output console.log(max_obj); |
Output:
{ 'n': 6 }
Example 2: In this example, we are printing the maximum value of ‘n’ of an array of objects by the use of the _.maxBy() method.
Javascript
// Requiring the lodash library const _ = require("lodash");Â
// Original array let arr = [{ 'n': 10 }, { 'n': 5 },{ 'n': 3 }, { 'n': 12 }];Â
// Use of _.maxBy() method let max_obj = _.maxBy(arr, 'n');Â
// Printing the output console.log(max_obj); |
Output:
{ 'n': 12 }
