Which method is generally used to convert JSON data back into a JavaScript object?

The method used to convert JSON data back into a JavaScript object is JSON.parse(). This function takes a string in JSON format and parses it, returning the corresponding JavaScript object. It is particularly useful when you receive data from a web server, which is commonly formatted as JSON.

For example, if you have a JSON string like '{"name": "Alice", "age": 25}', using JSON.parse() will transform that string into a JavaScript object that can be accessed via dot notation or bracket notation, allowing you to easily interact with the data.

Other provided options serve different purposes: JSON.stringify() is used to convert a JavaScript object into a JSON string, Object.create() is for creating a new object with a specified prototype, and Object.assign() is utilized for copying values from one or more source objects to a target object. Understanding these differences highlights the distinct role each method plays within JavaScript.
