Lodash _.minBy() Method

Lodash _.minBy() method is used to compute the minimum value from the original array by iterating over each element in the array using the Iteratee function. It is almost the same as the _.min() function.

Syntax:

_.minBy(array, [iteratee = _.identity]);

Parameters:

• array: It is the array that the method iterates over to get the minimum element.
• iteratee: It is the function that is invoked for every element in the array.

Return Value:

This method returns the minimum element.

Example 1: In this example, we are printing the minimum value of the given array by the use of the _.minBy() method.

// Requiring the lodash library  
const _ = require("lodash");

// Original array 
let arr = [{ 'n': 4 }, { 'n': 2 }, { 'n': 6 }];

// Use of _.minBy() method 
let min_val =
    _.minBy(arr, function (o) { return o.n; });

// Printing the output  
console.log(min_val); 

Output:

{ 'n': 2 }

Example 2: In this example, we are printing the minimum value of the given array by the use of the _.minBy() method.

// Requiring the lodash library  
const _ = require("lodash");

// Original array 
let arr = [{ 'n': 10 }, { 'n': 5 },
{ 'n': 3 }, { 'n': 12 }];

// Use of _.minBy() method 
let min_val = _.minBy(arr, 'n');

// Printing the output  
console.log(min_val); 

Output:

{ 'n': 3 }
