How to usea Custom Serializer Function in Javascript
In this approach, we create a custom serializer function that allows more control over how the JSON data is converted to a string. This can include additional custom processing, such as handling special data types or applying specific transformations to the data.
Example: In this example, we create a custom function that converts Date objects to ISO strings and omits the ‘password’ property.
const data = {
name: "John",
age: 35,
city: "New York",
birthdate: new Date("1989-06-15"),
password: "secret123"
};
function customStringify(obj) {
return JSON.stringify(obj, (key, value) => {
if (value instanceof Date) {
return value.toISOString();
}
if (key === 'password') {
return undefined;
}
return value;
});
}
const result = customStringify(data);
console.log(result);
Output
{"name":"John","age":35,"city":"New York","birthdate":"1989-06-15T00:00:00.000Z"}
