JavaScript has several data types that are used to store and manipulate different kinds of data. The following are the primary data types in JavaScript:
Numbers: Used to represent numeric values, such as 42 or 3.14. Numbers can be integers or floating-point values.
Strings: Used to represent text values, such as "Hello, World!" or "JavaScript is awesome!".
Booleans: Used to represent true/false values. Boolean values are often used in conditional statements and loops.
Undefined: Used to represent a variable that has been declared but has not been assigned a value. A variable can also have the value of undefined if it is accessed before it has been initialized.
Objects: Used to represent collections of key/value pairs. Objects can contain properties and methods that can be accessed and manipulated.
