JavaScript Leading Web Development

Data types and structures:-

bookmark_border Primitives are the simplest types of data in JavaScript. A primitive literal is a Value, with no wrapper or properties of its own. Primitive literals are immutable, meaning they can not be changed to represent other values in the same way that JavaScript's more complex object-based data structures can. For example, while the value of a variable named theTruth can be reassigned a value of false, the boolean literal true can never represent any value other than true, in the same way the number literal 5 can never represent the value of another number.

There are seven primitive data types:

Numbers

Strings

Booleans

null

undefined

BigInt Symbol
