Is there a term in JavaScript that denotes an object that can be serialized into JSON format?

Can you help me find a term for basic objects that accentuates their simplicity? Particularly, objects that do not reference themselves and do not have any methods or bindings (i.e. JSON-serializable).

The terms I am currently using are:

  1. "flat object"
  2. "simple object"
  3. "data container object"
  4. "JSON-serializable object"

I am not satisfied with them because:

  1. Suggests a lack of hierarchy, which is actually acceptable.
  2. Seems unclear.
  3. Also appears vague.
  4. Doesn't directly address complexity, but focuses more on requirements. While the ability to be JSON-serializable is sometimes a requirement, simplicity usually takes precedence.

Examples of objects I want to describe:

var good_1 = {};

var good_2 = {a: 1, b: 'str'}

var good_3 = {thing: [1,
                      {a: 1,
                       b: 'str'},
                      'word'],
              otherThing: 42};

Examples of objects I want to distinguish from:

var bad_1 = {thing: 3,
             getThing: function () { return this.thing; }};

var bad_2 = {a: 1};
bad_2['self'] = bad_2;

Inquiry

What should I name objects that do not reference themselves, contain no methods, bindings, etc (i.e. JSON-serializable)?

Answer №1

The Wikipedia page about serialization defines it as:

In the realm of computer science, serialization is the procedure of transforming data structures or object states into a format that can be saved and reconstructed later on in the same or a different computing environment. When this sequence of bits is read again following the serialization format, it can be utilized to generate an exact replica of the original object in terms of meaning. However, for complicated objects that heavily rely on references, this process can be quite intricate. The serialization of object-oriented objects excludes any associated methods they were formerly connected to.

Therefore, a serializable object essentially characterizes the kind of object displayed in your question, not only in JavaScript but also in various other programming languages.

Answer №2

Simple Data Structures.

SDS, as they are commonly referred to. These data structures consist solely of data fields and do not include any functionality. The concept is not tied to a specific programming language.

In discussions, SDSs are often compared to POJOs (Plain Old Java Objects), which have slightly different characteristics. According to this Wikipedia page, POJOs are essentially SDSs with accessor methods. However, there is some debate on this definition when researched further.
