What data types are in JSON?

The main data types in JSON are:

• Object — a set of key-value pairs, where the key is a string and the value can be any JSON type. Objects are enclosed in curly braces {}.
• Array — an ordered list of values, enclosed in square brackets [].
• String — a sequence of characters in double quotes.
• Number — integers or floating-point numbers, without quotes.
• Boolean — values true or false.
• Null — a special value null, indicating the absence of a value.

Example of JSON with different types:

{
  "name": "Ivan",
  "age": 30,
  "isEmployee": true,
  "projects": ["Project1", "Project2"],
  "address": null
}
