The Lodash _.functionsIn() method creates an array of function property names from own and inherited enumerable properties of the given object.
Syntax:
_.functionsIn( object )
Parameters: This method accepts two parameters as mentioned above and described below:
- object: This is the object to inspect.
Return Value: This method returns an array of properties.
Example 1:
Javascript
// Defining Lodash variable const _ = require( 'lodash' ); // Defining object function function GFGfunc() { this .Geek1 = _.constant( 'gfg' ); this .Geek2 = _.constant( 'gfg' ); } // Use of function console.log(_.functionsIn( new GFGfunc)); |
Output:
[ 'Geek1', 'Geek2' ]
Example 2:
Javascript
// Defining Lodash variable const _ = require( 'lodash' ); // Defining object function function GFGfunc() { this .Geek1 = _.constant( 'gfg' ); this .Geek2 = _.constant( 'gfg' ); } GFGfunc.prototype.Geek3 = _.constant( 'gfg' ); // Use of function console.log(_.functionsIn( new GFGfunc)); |
Output:
[ 'Geek1', 'Geek2', 'Geek3' ]
Note: This will not work in normal JavaScript because it requires the lodash library to be installed and can be installed using npm install lodash.
