[[object Object]]

There are three ways to see inside object that:

Log to console with console.log(<your-object-name.
Stringify it with JSON.stringify(<your-object-name.>)
Use for…in loop and look at each individual property.

console.log('string', object)

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

    age: 7

// All keys will be turned into strings!

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

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

[object Object]

Comment

[object Object]
/* 
	This means that your programming interpreter doesn't support showing
	JSON parsers somewhere, and has resorted to the default object representation
	behavior (see below).
	Behavior: [object CLASS]
	Since it's an object, well: [object Object]
	This is most commonly seen in a depraved, deranged state in objects
    ingrained into text. We still haven't really devised a prophecy
    about why it still happens in some places. Either JavaScript likes to
    be vexing by being "open" aka adding unnecessary steps, or JavaScript
    has something like security issues related to its code/some other
    predicament retaining and pertaining.

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
