Json serves as a serialization tool that facilitates the conversion of objects into strings and back again.
Consider, for instance, a variable named Person:
var person = {
Firstname: "Mike",
Surname: "Smith"
};
var json = JSON.stringify(person);
Once converted, it appears as follows:
{"Firstname":"Mike","Surname":"Smith"}
To reverse the process, we can deserialize by running:
var person2 = JSON.parse(json);
This ability to encode objects as strings enables seamless data exchange with various systems such as web services, databases, and messaging platforms. Json effectively acts as a universal language facilitating communication between disparate systems.
