What are some examples of using JSON.stringify in JavaScript?

Can you give me some examples of how to use JSON.stringify in JavaScript?

Sure! JSON.stringify is used to convert a JavaScript object into a JSON string. For example, if you have an object like this: { name: 'Alice', age: 25 }, you can stringify it using JSON.stringify(obj).

What happens if the object has a function in it?

If the object contains a function, JSON.stringify will ignore it. For instance, if you have { name: 'Alice', greet: function() { return 'Hello'; } }, the resulting JSON string will only include the 'name' property.

Can you show me how to handle circular references?

To handle circular references, you can use a replacer function with JSON.stringify. For example, you can keep track of seen objects and avoid stringifying them again.

What about formatting the output?

You can format the output by passing additional parameters to JSON.stringify. For example, JSON.stringify(obj, null, 2) will pretty-print the JSON with an indentation of 2 spaces.
