Lodash _.at() Method

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, collection, strings, lang, function, objects, numbers etc. The _.at() method creates an array of values corresponding to paths of object. Syntax:

_.at(object, [paths])

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

object: It holds the object to iterate over.
[paths]: It holds the property paths to pick.

Return Value: This method returns the picked values. Example 1: Here, const _ = require(‘lodash’) is used to import the lodash library in the file.

javascript

// Requiring the lodash library 
const _ = require("lodash"); 
     
// Original array 
var object = { 'p': [{ 'q': { 'r': 7 } }, 9] };

// Using the _.at() method
let at_elem = _.at(object, ['p[0].q.r', 'p[1]']);

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

Output:

[ 7, 9 ]

Example 2:

javascript

// Requiring the lodash library 
const _ = require("lodash"); 
     
// Original array 
var object = { 'oppo': [{ 'vivo': { 'moto': 1900 } }, 2400] 

};

// Using the _._.at() method
let at_elem = _.at(object, ['oppo[0].vivo.moto', 'oppo[1]']);

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

Output:

[ 1900, 2400 ]

Note: This code will not work in normal JavaScript because it requires the library lodash to be installed.
