Lodash _.functionsIn() Method

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.
