Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.
The _.prototype.at([paths]) method of Sequence in lodash is the wrapper version of _.at() method which creates an array of values analogous to the specified paths of an object.
Syntax:
_.prototype.at([paths])
Parameters: This method accepts a single parameter as described below:
- [paths]: It is the paths property which is to be chosen.
Return Value: This method returns the new lodash wrapper instance.
Example 1:
Javascript
// Requiring lodash library const _ = require( 'lodash' ); // Creating an object variable var obj = { 'x' : [{ 'y' : { 'z' : 5 } }, 6] }; // Calling at() method let result = _(obj).at([ 'x[0].y.z' , 'x[1]' ]).value(); // Displays output console.log(result); |
Output:
[ 5, 6 ]
Example 2:
Javascript
// Requiring lodash library const _ = require( 'lodash' ); // Creating an object variable var obj = { 'Geeks' : [{ 'for' : { 'Geeks' : 5 } }, 13] }; // Calling at() method with its parameter let result = _(obj).at([ 'Geeks[0].for.Geeks' , 'Geeks[1]' ]).value(); // Displays output console.log(result); |
Output:
[ 5, 13 ]
Example 3:
Javascript
// Requiring lodash library const _ = require( 'lodash' ); // Calling at() method with its parameter let res = _({ 'b' : { 'c' : 33 } }) .at([ 'b.c' ]).value(); // Displays output console.log(res); |
Output:
[ 33 ]
