Can't get a grasp on JavaScript prototype

JavaScript
#1

Hello, I have finally gotten to the OOP section in the curriculum. I understand objects, but can’t get a grasp on prototype. Can someone explain it in a beginner friendly way, or is there a resource online that describes it in a beginner friendly way?

#2

Found this article, hopefully it will shed a bit more light

Prototypes

#3

Also look at the reply immediately after it as well which clarifies some of the terms (I was a bit clumsy with the description)

#4 
function Programmers(gender, age, firstName, lastName, favourite_lang){
  this.gender = gender;
  this.age = age;
  this.firstName = firstName;
  this.favourite_lang = favourite_lang;
  this.lastName = lastName
}

Programmers.prototype.getName = function(){
  return this.firstName + " " + this.lastName;
}

Programmers.prototype.numLegs = 2;

let p1 = new Programmers("male", 46, "James", "cook",  "Go");
let p2 = new Programmers("female", 16, "Peter", "parker", "JavaScript");
let p3 = new Programmers("male", 35, "Eryc", "ramsay", "Python");


console.log(p1.getName);

When i console log it logs function getName() instead of James cook. Have i done this correctly?

#5

You mentioned that programmers use the class syntax instead of OOP. Why is that?

#6

No, OOP is just a style of programming – the syntax used doesn’t change that. The way it is taught on FCC shows how it works. But normally in practice you would use the syntax for classes (class MyClass {), which does exactly the same thing, just code written using class tends to be easier to read and write.

#7

Can you review the code i posted above, and tell me if its correct?

#8 
Programmers.prototype.getName = function(){

getName is a function, so your log is telling you what it is. How would you use a function?

#9

Oh damn, I forgot the brackets :unamused:
