Lodash - maxBy method

Syntax

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

Arguments

• array (Array) − The array to iterate over.

• [iteratee=_.identity] (Function) − The iteratee invoked per element.

Output

• (*) − Returns the maximum value.

Example

var _ = require('lodash');
var values = [{ 'n': 1 }, { 'n': 2 }];
var result = _.maxBy(values, function(o) { return o.n; });

console.log(result);
 
result = _.maxBy(values, 'n');
console.log(result);
