There are two types of languages.

A primitive type is predefined by the language and is named by a reserved keyword. Primitive values do not share state with other primitive values. The eight primitive data types supported by the Java programming language are: byte: The byte data type is an 8-bit signed two's complement integer.

String—any number of characters, for example "a", "one", "one 2 three". Boolean—can be either true or false. JavaScript Data Types The JavaScript language has two kinds of types: primitive types and reference types. Primitive types (termed as value types too) are stored as simple data types while reference types are stored as objects, which means it holds a reference to a memory's location. Alex Sablan May 27, 2021 We will cover the 7 primitive data types in javascript. A primitive data type can be described as a fundamental type used in a programming language that cannot be broken down any further. For example, a number is a primitive data type, whereas a map is an object that holds key-value pairs and order of the keys.

Primitive Data Types. Data Type null indicates that there is an object missing or invalid. Special primitive type having additional usage for its value: if the object is not inherited, then null is shown; Data Type undefined as the naming indicated, the value is yet not defined. Data Type Boolean can only have two values true or false. A primitive. Is a value of a primitive type. There are 7 primitive types: string, number, bigint, boolean, symbol, null and undefined. An object. Is capable of storing multiple values as properties. Can be created with {}, for instance: {name: "John", age: 30}. There are other kinds of objects in JavaScript: functions, for example, are objects. The Concept of Data Types. In programming, data types is an important concept. To be able to operate on variables, it is important to know something about the type. Without data types, a computer cannot safely solve this:

Non-Primitive Values — aka Complex/Special Values. In JavaScript, objects and functions are considered non-primitive values. In JavaScript, data types fall into two categories: primitive data types and objects and they behave very differently. All primitive types are immutable (values incapable of being changed), while objects are mutable. Primitive values are important for application performance.
