How can you customize the output of JSON.stringify for objects in JavaScript?

What steps can be taken to customize the default output of JSON.stringify for an object?

Answer №1

If you want to customize how your object is stringified, you can use a "replacer" function with specific logic for your object type. For more information, refer to the documentation provided at: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#The_replacer_parameter

Here's an example taken from the documentation:

function customReplacer(key, value) {
  if (typeof value === 'string') {
    return null;
  }
  return value;
}

var sampleObject = {brand: 'Apple', product: 'iPhone', year: 2021, price: 999};
var jsonStringOutput = JSON.stringify(sampleObject, customReplacer);
