# Overview
The **`fromEntries`** function is defined in the `Object` class in JS. The `fromEntries` function converts an iterable object to a JS object.
# Syntax
```js
Object.fromEntries(iterable);
```
# Parameters
- **`iterable`** is an object that implements the iterable protocol such as `Array` or `Map`.

# Return value
- A JS `Object` that contains the key-value pairs returned by the passed `iterable`.

# Description
The `fromEntries` function takes an `iterable` object and converts it into a JS `Object`. `iterable` is an object that can produce an `iterator` object. An **iterator** is a 2 element array, where the first index element represents the key and the second index element represents the value.

# Example
The following code converts an `Array` to an `Object`.

let arr = [['0', 'S'], ['1', 'H'], ['2', 'O'], ['3', 'T']];
let obj = Object.fromEntries(arr);

console.log('Array:', arr);
console.log('Object:', obj);

## Output
```bash
Array: [['0', 'S'], ['1', 'H'], ['2', 'O'], ['3', 'T']]
Object: {0: 'S', 1: 'H', 2: 'O', 3: 'T'}
```

In the example above, the `arr` variable contains an `Array` that has four 2 element arrays that represent an `iterator`. The `Object.fromEntries` function converts the `arr` to an `Object`. The first element of all the arrays inside `arr` become the key of `obj`, and the second element of all the arrays inside `arr` become the respective values of `obj`.

What is Object.fromEntries() in Javascript?

Converts an iterable like an Array or Map into a JS object using key-value pairs.
