JavaScript Data Types. JS full course Data Types basic to advance - জাভাস্ক্রিপ্ট বাংলা টিউটোরিয়াল

Описание: In JavaScript or in any programming language, the concept of data types is important. Data types are the different kinds of data that can be stored or used in a JavaScript program.
String Data Type
The string data type is a sequence of characters used to represent text.String can be written with either single or double quotes. You can use which one you like. But if the string contains single quotes, use double quotes. Or if it contains double quotes, use single quotes.
Number Data Type
The number data type is an integer or a floating point number (number with decimal). Combining Strings and Numbers. Combining a string and a string returns a string. Combining a number and a number returns a number. Combining a string and a number returns a string. Since JavaScript evaluates from left to right, different sequences produce different results.
Boolean Data Type
The Boolean data type is a logical data type that can only have true or false as values.
The undefined Data Type
If a variable has no assigned value, the value is undefined.
The null Data Type
The null data type is a special data type denoting a null value — meaning it's not an empty string "" or 0.
Object Data Type
In this lesson, we will only learn the most basic concepts of JavaScript Objects., that will teach it in depth. The object data type is a collection of related data. A JavaScript array is a collection of values. Each value is separated with a comma (,).
Variables are not directly associated with a single data type, unlike in other programming languages.
Any variable in JavaScript can be reassigned to values of all types. The typeof returns a string indicating the data type of the evaluated operand.
Primitive Data
There are 4 basic primitive data types:
string
number
boolean
undefined
Complex Data
There are two complex data types, both can be returned by the typeof operator:
object
function
