What is the best way to define objects containing arrays of objects in JavaScript?

I am seeking to create a blueprint for the following data structure, with all values provided by the user:

{
  "name":"ABC",
  "city":"X", 
  "child": [{"name":"ccc","age":"22"}, {"name":"ccc","age":"22"} ]
}

This data structure consists of a parent object containing attributes for name and city, as well as an array of child objects with attributes for name and age.

To clarify, I am looking for the syntax or declaration details for the parent and child object arrays.

Answer №1

When declaring a nested array, you are essentially creating a structure where the higher level array serves as a parent object with properties that represent child objects within.

This method is commonly used when working with arrays.

If you're interested in using a constructor or a single-line invocation, consider exploring ES6 classes: https://www.geeksforgeeks.org/es6-classes/
