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:
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.
