# Objects in JavaScripts

There are 7 data types in JavaScript namely :-

- number
-string
- null
- undefined
- boolean
- **object**
- symbol

We will be looking at object data type, declaration, properties and various operation that can be performed on objects. There is a popular quote in the JS community which says 
>Almost Everything is an Object 


# But first what is an Object?
Objects are used to store collection of various data where the **value **of each data is accessed via a *key*. sounds cool right 😎 ? let's dig further.

# Objects can neither be created nor 🙄 ...
so how do we created an object? we simply create an object as shown below

```
const club = new Object(); //using the object constructor
const club= {} //using the object literal syntax
``` 


# Populate object with data 
we populate the object by adding a key and creating a value. the value can be of data types such as numbers, strings, arrays or even object yeah i said it objects. take for example the code below, we created a variable **club** which is an object that holds data about the one of the successful clubs in England 😉

```
const club = {
name: "Manchester United", 
nickname: "The Red Devils",
founded: 1878,
premierLeague: 20,
coach: {
 name: "Ole Gunner Solskjear",
age: 42,
previousCLubs: ["Molde FK", "Cardiff City"]
  },
rivals: ["Leeds United", "Liverpool", "Manchester City"],
previouslyRelegated: true,
website: "manutd.com"
 
}

```

# How to access our data 
we can access the data in our collection using :
- dot notation(.)
- Square bracket notation([ ])
referencing the keys in the object

```
//using dot notation
console.log(club.name);  // Manchester United

//using square bracket notation
console.log(club["name"]); // Manchester United
```

# Destructuring an Object {extracting data}
Destructuring can simply be defined as  method of extracting data from an Object or Array  and that data can be assigned to a variable as seen below

```
// using the dot notation, remember?
const club = club.name; // Manchester United
const nickname = club.nickname; // The Red Devils

```

the above code can even be written in a better way using ES6 destructuring expression

```
const {club, nickname } = club;

```
so a little explanation to the above code ...
we created two variables enclosed in a curly bracket and made it equal to the object's name
**!IMPORTANT NOTICE** the new variable names (club and nickname) declared must be a key in the Object

lastly,

# Delete Object properties
properties of an object can be deleted by using the delete keyword as shown below
```
delete club.previouslyRelegated; // deletes the key and value
```
