What are the Datatypes in JavaScript– We all know that JavaScript is a dynamically typed language, meaning the variable can hold a value of different data types and change types during the script’s execution. In JavaScript, the data types are divided into two main groups: primitive and Non-primitive. In JavaScript, data types represent different kinds of values. In today’s article, we will learn about JavaScript types and their unique characteristics.
what are the 7 data types in JavaScript?
We all know that JavaScript data types are divided into primitive and Non-primitive types.
primitive data types:
primitive data types can hold single values like string, number, BigInt Boolean, undefined, null, and symbol these are the primitive data types.
Non-primitive data types:
Non-primitive data types can hold multiple values object are Non-primitive data types. Now let’s see in depth what is data types in JavaScript.
primitive data types: What are the Datatypes in JavaScript
primitive data types store single values that are immutable.
Number: Number represents integer and floating point number.
string: string represents a sequence of characters that is used for textual data. Strings can be defined as single quotes(‘), double quotes (“), or backticks ( ` ).
Boolean: Boolean represents logical values it can be either true or false.
Undefine: in an undefined data type variable is not initialized.
Null: The Null data type denotes a null value. it refers to the non-existence of any value.
Symbol: A symbol is a unique and immutable value symbol used as an identifier for object properties.
Bigint: Big int allows the representation of integers beyond the number range.
Non-primitive data types: Datatypes in JavaScript
Non primitive data types are objects that store multiple values non primitive data types are unlike primitives they are mutable they can Store collections of data.
Object: objects the collection key value Pairs. objects represent Complex structures just like arrays, functions, or more structures.
Array: An array it’s a special type of object that holds an ordered collection value which can be any data type array that is zero Indexed.
function: functions can be stored In variables it fast as arguments, and returned by other functions. function is a special object representing executable code.
