What is the purpose of JSON.stringify in JavaScript?
JSON.stringify is used to convert a JavaScript object into a JSON string, making it easier to transmit data.
Can you give me an example of how to use JSON.stringify?
Sure! If you have an object like const obj = { name: 'Alice', age: 25 };
, you can use JSON.stringify(obj)
to get a string representation: '{"name":"Alice","age":25}'
.
Are there any options I can use with JSON.stringify?
Yes, you can pass a replacer function or an array of strings as the second argument, and a space value for pretty-printing as the third.
What happens if I try to stringify a function?
Functions are not serializable in JSON, so they will be omitted from the resulting string.
