javascript object

Comment

/*
An object is made of key value pairs. Keys can be strings 
(which don't require quotes), array with a string, or symbols. Values can be arrays,
objects, numbers etc
*/

let testSymbol = Symbol('item number 3')

const obj = {
	item1: 1,
    "item number 2": 2,
    testSymbol: 3,
  	['a']: 4
}

// Another way of creating an object:
const obj = new Object();
obj.name = 'John'

// To access values, you can use dot notation or bracket notation. 
// Both do the same thing, bracket notion is useful for multispace keys,
// keys with dashes, or accessing values using variables
> obj.item1
> obj['item number 2']

> let b = 'item1'
  obj[b]
  // The following would NOT work and would return undefined:
  obj.b

// Checking exsistence of keys in object:
obj.toString ----- checks values of object and whatever object inherits from
> returns true

obj.hasOwnProperty('toString') ----- checks values of object only. Do this instead of checking like: (obj.name !== undefined)
> returns false


// Short hand key assignment:
const name = 'John'
const obj2 = {
    // this is short hand that automatically sets the key to be 'name',
    // and it's value to be 'John'
	name, 
}

// Constructor objects:
function Obj(name, age){
	this.name = name
  	this.age = age
}

const person = new Obj('john', 1)

// adding functions, couple ways:
const obj = {
  	name: 'Mike',
  	number: 4421,
	sayHi: () => console.log('hi'),
  	sayBye() {
    	console.log('say bye')
    },
    // getter function to get values from object. Has different usecases, but the same as doing obj.number
  	get getNumber(){
    	return this.number
    }
    // setter function to set values in object. Has different usecases, but the same as doing obj.number = 152
    set setNumber(num){
    	this.number = num
    }
}

obj.sayHi()
obj.sayBye()
obj.getNumber //Note how it's being accessed like a standard property, and not a function
obj.setNumber //Note how it's being accessed like a standard property, and not a function

// To make an object literal:
const dog = {

    breed: "unknown",
    isAlive: false,
    age: 7

// All keys will be turned into strings!

// To retrieve a value:
dog.age; //7
dog["age"]; //7

//updating values
dog.breed = "mutt";

what is an object in javascript

Comment

Objects are the collection of properties which contain values as key:value pairs.
A property is also like a variable which stores data, but in property we stores
data in key:value pair i.e, age:21
We access property of an objects by object_name.property_name

what is object in js

Comment

// JavaScript objects are a fundamental data structure used to represent various entities.
// They have properties that can be used to store key-value pairs of data.

// Create an object using object literal notation
const person = {
  name: "John",
  age: 25,
  city: "New York"
};

// Accessing object properties
console.log(person.name);  // Output: "John"
console.log(person.age);   // Output: 25

// Adding a new property to the object
person.gender = "Male";

// Updating an existing property
person.age = 26;

// Deleting a property
delete person.city;

// Looping through object properties
for (let key in person) {
  console.log(key + ": " + person[key]);
}

// Output:
// name: John
// age: 26
// gender: Male
