I have 3 objectos in an array.each object has two properties (name and surname). I need to show a console.log with completed name for each object but using a object construtor.

const people = [
        {
            nome:'Raquel',
            sobrenome:'Santos'
        },
        {
            nome:'André',
            sobrenome:'Almeida'
        },
        {
            nome:'Minerva',
            sobrenome:'McGonadall'
        }
    ]

    const Persons = function(name, surname) {
        this.nome = name
        this.sobrenome = surname
    }

    people.forEach(function(item) {
        // I stoped here 
        return item = new Persons            
    })

I added a function for writing to log.

    const people = [
        {
            nome:'Raquel',
            sobrenome:'Santos'
        },
        {
            nome:'André',
            sobrenome:'Almeida'
        },
        {
            nome:'Minerva',
            sobrenome:'McGonadall'
        }
    ]

    const Persons = function(nome, surname) {
        this.nome = nome
        this.sobrenome = surname
    }
    
    Persons.prototype.log = function() {
      console.log(this.nome + " " + this.sobrenome);
    };

    people.forEach(function(item) {
        let person = new Persons(item.nome, item.sobrenome);
        person.log();
    })

How are objects in JavaScript stored in memory?, begins with { (left brace) and ends with } (right brace). Each name is followed by : (colon) and the name/value pairs are separated by , (comma). So, to create an object using the ‘new’ keyword, you need to have a constructor function. Here are 2 ways you can use the ‘new’ keyword pattern — a) Using the ‘new’ keyword with’ in-built Object constructor function. To create an object, use the new keyword with Object() constructor, like this: const person = new Object();

You may create a class with a method getFullName.

You may have a look, as well, to the different languages of properties and choose only a single one for the whole code.

Your gioven data is converted in the callback for creating an instance of a person.

class Person {
    constructor (name, surname) {
        this.name = name;
        this.surname = surname;
    }
    
    getFullName () {
        return [this.surname, this.name].join(' ');
    }
}


const
    peoples = [{ nome: 'Raquel', sobrenome: 'Santos' }, { nome: 'André', sobrenome: 'Almeida' }, { nome: 'Minerva', sobrenome: 'McGonadall' }],
    persons = peoples.map(({ nome, sobrenome }) => new Person(nome, sobrenome));

persons.forEach(person => console.log(person.getFullName()));

Objects in Javascript, and methods, respectively, in the context of an object. Now, let’s define a property name on the person1 object. person1.name = "Anil" console.log(person1.name)//Output: Anil console.log(person2.name)//Output: Ashwin. Here person1.name outputs

in the foreach:

console.log(item.nome+' '+item.sobrenome)

JavaScript Objects, and method). For example: car, pen, bike, chair, glass, keyboard, monitor etc. JavaScript is an object-based language. Everything is an object in JavaScript. Object Types (Blueprints) (Classes) The examples from the previous chapters are limited. They only create single objects. Sometimes we need a "blueprint" for creating many objects of the same "type". The way to create an "object type", is to use an object constructor function. In the example above, function Person() is an object constructor

const Persons = function(name, surname){
    this.nome = name
    this.sobrenome = surname
    return name + ' ' + surname
}

console.log(new Persons('Raquel', 'Santos'))

I'm unsure why you'd need to have to console log via the Object's constructor. Luca C.'s answer is more straight forward.

How to Add, Modify, or Access JavaScript Object Literal Properties, [[Prototype]]: Each object that is accessed by the running context has a Chapter 6: JavaScript Classes, that you can create objects by using a constructor function. console.log(student2) var student2 = The function Student is the constructor It includes the first name and last name parameters, or in this case, properties. Where pupup will show with print option. JavaScript help to use a print function of the window object. You just need to call a window.print() prints the current web page. Let’s see the example code. Use input tag where value=”print” attribute. Also adding a <script> tag for which will not show confirmation popup after click print button.

Starting with ES2015 you can also hack your way with Object.setPrototypeOf(). Also, providing an own toString() may be a natural choice for this kind of task, see how "Before" and "After" loops are identical.

const people = [
  {
    nome:'Raquel',
    sobrenome:'Santos'
  },
  {
    nome:'André',
    sobrenome:'Almeida'
  },
  {
    nome:'Minerva',
    sobrenome:'McGonadall'
  }
];

console.log("Before:");
people.forEach(function(folk,idx){
  console.log(idx+": "+folk);
});

function Person(){}
Person.prototype.toString=function(){
  return this.nome+" "+this.sobrenome;
};

const proto=new Person();

people.forEach(function(folk){
  Object.setPrototypeOf(folk,proto);
});


console.log("After:");
people.forEach(function(folk,idx){
  console.log(idx+": "+folk);
});

console.log("people[0] instanceof Person: "+(people[0] instanceof Person));

JavaScript for Gurus: Use JavaScript programming features, , When we use a forin statement to iterate an instance of an object to a, it will Furthermore, any instance objects constructed by the derived constructor (d) will be _super); function SuperHero(name, surname, superpower) { _super.call(this​, return "I'm using my " + superpower; console.log(derived.method1); // 1 const​  Python Exercises, Practice and Solution: Write a Python program to display your details like name, age, address in three different lines.

Learning TypeScript 2.x: Develop and maintain captivating web , To enable this, objects can have let bindings that are internal to the object, but when logging the objects construction, you must prefix the function call with the do a function with a side effect, you can print the user's fullName to the console: it's constructor takes three parameters, the user's // first name, last name and a​  Objects, in JavaScript, is it’s most important data-type and forms the building blocks for modern JavaScript. These objects are quite different from JavaScript’s primitive data-types(Number, String, Boolean, null, undefined and symbol) in the sense that while these primitive data-types all store a single value each (depending on their types).

Beginning F#, In JavaScript, objects penetrate almost every aspect of the language. let user = new Object ( ) ; // "object constructor" syntax let user = { } ; // "object let user = { // an object name : "John" , // by key "name" store value In the example above, properties have the same names as variables. console.log(+x) Select element is written using <select> tag and multiple select element uses multiple attribute as <select multiple>. By default select element compares two objects using object identity. If we want to change the default behavior, we need to use compareWith input in select element. Now find the complete example step-by-step.

Objects, displayName property returns the display name of the function. Do not use it on production sites facing the Web: it will not work for every user. displayName = '​Show Popup'; console.log(popup. var object = { // anonymous someMethod: function(value) Standard built-in objects · Function; Properties. In this tutorial, we will show you how to create observable using create, of, from operators in Angular. We can use them to create new observable from the array, string, object, collection or any static data.

Comments
  • I want to show in console.log the existed objects by using a constructor object - why? Constructors are not really related to printing.
  • This is only an exercise. I am newbie .so I just wanted to see the result of my exercise and sometimes I dont know how to see the result and where to insert the code
