## `Object.fromEntries`

This method is used to convert an array of key-value pairs into an object.

* The `fromEntries` method takes an #key# argument: which is an iterable object such as an array, Map, or object that implements the iterable protocol #key#.
* The `fromEntries` method returns a new object created from the iterable object passed as an argument.

### Creating an Object from an array

let emojis = [ ['love' , '💕'], ['happy', '😊 '] ];
let emojisObj = Object.fromEntries(emojis);
console.log(emojisObj);

console

let map = new Map([ ['love' , '💕'], ['happy', '😊 '] ]);
let emoji = Object.fromEntries(map);
console.log(emoji);

### Tip: Shallow clone an Object

We can use `fromEntries` to clone an object. To do this, you need to convert the object to entries and create the object using `fromEntries`.

let user ={
    name : "Balaji",
    age : 23,
};
let entries = Object.entries(user);
console.log("Entries is", entries);
let clonedObj = Object.fromEntries(entries);

console.log("\nObject cloned");

clonedObj.age = 24;
console.log("\nAfter setting clonedObj.age = 24", clonedObj.age);

console.log("\nAfter setting conedObj.age=24", user.age);

Make sure that only the key-value pair is passed; otherwise, there will be an error. 

#### The below code will throw an error
```
// TypeError will be thrown in all the below case 
Object.fromEntries(undefined)
Object.fromEntries(null)
Object.fromEntries(true)
Object.fromEntries(100)
Object.fromEntries("hi")
Object.fromEntries({key: "value"})
Object.fromEntries([1,2,3])
```
