Final answer:
In JavaScript, the five primitive data types are String, Number, Boolean, Undefined, and Null. These types are essential for representing simple values and serve as the foundation for all variables in JavaScript.
Step-by-step explanation:
Primitive Data Types in JavaScript
In JavaScript, there are five primary primitive data types that are used to represent simple values. These data types are:
String: This type is used for representing text. It must be enclosed in quotes, for example, 'Hello, World!'.
Number: This is used for representing numerical values, both integers and floating-point numbers, like 42 or 3.14.
Boolean: It has two possible values: true and false. Booleans are often used in conditional statements.
Undefined: This type is automatically assigned to variables that have been declared but not initialized with a value.
Null: It represents the intentional absence of any object value, and is typically assigned by the programmer to indicate 'no value'.
Each of these data types is distinct in how they represent and store the value attributed to them, and they serve as the building blocks for variables to hold specific types of data in JavaScript.
