## Overview
The **`JSON.parse()` method**  parses a JSON string into a JavaScript value or object.

## Syntax
```
JSON.parse(jsonString, reviver);
```

## Parameters
This method accepts the following parameters:
* **`jsonString`**: This is the JSON string that needs to be parsed into a JavaScript value or object.
* **`reviver`**: This is an optional function to perform some transformation on the parsed object before returning it. 

## Return value
This method returns a JavaScript value or object corresponding to the JSON string. 

If the JSON string is malformed, a JavaScript exception is thrown. A few examples of a malformed JSON string are:
1. A JSON string with trailing commas. In this case, this method returns a syntax error.
```
JSON.parse("{ name: Shubham,}")
```
2. A JSON string having single quotes. In this case, this method will return a syntax error.
```
JSON.parse("{ 'name': 'Shubham'}")
```

## Example
Let's look at an example of the `JSON.parse()` method in the code snippet below:

<html>
 <head>
   <title>jQuery | parseJSON() example</title>
 </head>
 <body>
   <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
 </body>
</html>

// create a JSON string
const jsonString = `{
  "name": "Shubham Singh Kshatriya",
  "designation": "Software Engineer"
}`

// print the type of jsonString on console
console.log("Type of jsonString", typeof jsonString);

// convert jsonString to JavaScript object
const parsedObject = JSON.parse(jsonString)

// print the type of parsedObject on console
console.log("Type of parsedObject", typeof parsedObject);

## Explanation
* Lines 2–5: We create a string, `jsonString`.
* Line 8: We print the type of `jsonString` on the console.
* Line 11: We use the `JSON.parse()` method to parse `jsonString` into a JavaScript object.
* Line 14: We print the type of `parsedObject` on the console.

## Output
We can see that `jsonString` has the string type and `parsedObject` has the object type. Therefore, we parse a JSON string into a JavaScript object.
