How does lodash.functions work?

lodash.functions is a method from the Lodash library that returns an array of all the function property names of an object, including inherited ones. When called, it takes an object as its argument and returns an array of strings representing the names of all the object's own and inherited function properties. It does not include any properties that are not functions.

// => Logs 'a' then 'b'.


const forOwnRight = _.forOwnRight({ 'a': 1, 'b': 2 }, (value, key) => console.log(key));
// => Logs 'b' then 'a'.


const functions = _.functions(_);
console.log(functions); // => ['add', 'after', 'ary', 'assign', ...]


const functionsIn = _.functionsIn(_);
console.log(functionsIn); // => ['add', 'after', 'ary', 'assign', ...]

const _ = require("lodash");

function Person(name, age) {
  this.name = name;
  this.age = age;
  this.speak = function () {
    console.log(`Hi, my name is ${this.name} and I am ${this.age} years old.`);
  };
}

console.log(_.functions(new Person("John", 25))); // output: [ 'speak' ]

In this example, we first require the lodash library. We then define a Person constructor function with name and age parameters. Inside the constructor, we define a speak method on the Person prototype. We then call _.functions with an instance of the Person constructor. This returns an array of function names defined on the instance, in this case just speak.
