How to use JSON.stringify() Function In MongoDB
The JSON.stringify()
function converts an object into a JSON-formatted string. This method is useful for generating compact, stringified representations of objects for logging or data manipulation purposes.
Syntax:
const jsonString = JSON.stringify(object_to_print);
print(jsonString);
Explanation:
- The JSON.stringify() function takes an object and converts it into a string representation in JSON format.
- It provides a more compact output compared to printjson().
- The print() function then displays the resulting JSON string.
Example of Printing a Nested Object
const user = {
_id: ObjectId("5dbe9b000000000000000001"),
name: "Bob",
address: {
street: "123 Main St",
city: "Los Angeles",
state: "CA"
}
};
const userString = JSON.stringify(user);
print(userString);
Output
Explanation: The output shows the entire object, including the nested address object, as a single JSON string. Note that ObjectId values might be represented differently depending on your MongoDB version.
