What are the differences between JSON.parse and eval?

Can you explain the differences between JSON.parse and eval?

Sure! JSON.parse is a method to safely parse JSON strings into JavaScript objects, while eval executes JavaScript code represented as a string.

Why is JSON.parse considered safer than eval?

JSON.parse only processes valid JSON data, preventing execution of arbitrary code, whereas eval can run any JavaScript code, which can be risky.

Can you give an example of when to use each?

Use JSON.parse when you receive JSON data from an API. Use eval only when you absolutely trust the source of the code being executed.

Are there any performance differences between the two?

Yes, JSON.parse is generally faster and more efficient for parsing JSON, while eval can be slower due to the overhead of executing code.
