Lodash _.method() Method
  • Last Updated : 14 Sep, 2020

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.

The _.method() method creates a function that invokes the method at the path of a given object. Any additional arguments are provided to the invoked method.

Syntax: 

_.method(path, args)

Parameters: This method accepts two parameters as mentioned above and described below:

  • path: This is the path to invoke.
  • args: These are the arguments to invoke the method with.

Return Value: This method returns the new invoker function.



Example 1:

Javascript




// Requiring the lodash library  
const _ = require("lodash");              
  
// Use of _.method() method 
var gfg = [
    'a': { 'b': _.constant("geeks") } },
    'a': { 'b': _.constant("for") } },
    'a': { 'b': _.constant("geeks") } }
];
          
let ans = _.map(gfg, _.method('a.b'));
     
// Printing the output  
console.log(ans);

Output:

["geeks", "for", "geeks"]

Example 2:

Javascript




// Requiring the lodash library  
const _ = require("lodash");              
  
// Use of _.method() method 
var gfg =[ 
    'b': _.constant(1) }, 
    'b': _.constant(5) },
    'b': _.constant(8) }
];
          
let ans = _.map(gfg, _.method(['b']));
     
// Printing the output  
console.log(ans);

Output :

[1, 5, 8]
