The tutorial includes a practical demonstration of these methods, showing how to convert a JSON object to a string and back to an object. It highlights the importance of these methods in web development, especially when dealing with data from servers.

What is the primary purpose of the JSON.stringify method in JavaScript?

• To validate JSON data

• To convert a string into a JSON object

• To convert a JSON object into a string

Why might you use JSON.stringify when dealing with cookies or session variables?

• Because it converts the data into a string format

• Because it encrypts the data

• Because it compresses the data

• Because it parses the data into an object

What does the JSON.parse method do?

• Encrypts JSON data

• Converts a string into a JSON object

• Converts a JSON object into a string

• It is not compatible with JavaScript

• It takes up more storage space

• You cannot access object properties directly

In what scenario might you need to use JSON.parse after receiving data from a server?

• When the data is already in object format

• When the data is in string format

• When the data is encrypted

• When the data is compressed
