## jAVA SCRIPT SERIES
## Arithmetic Operators
**Addition (+)**: Adds two numbers.
**Subtraction (-)**: Subtracts one number from another.
**Multiplication (*)**: Multiplies two numbers.
**Division (/)**: Divides one number by another.
**Modulus (%)**: Returns the remainder of a division.
**Exponentiation (**)**: Raises a number to the power of another.
**Increment (++)**: Increases a number by one.
**Decrement (--)**: Decreases a number by one.
**Unary Plus (+)**: Converts a value to a number.
**Unary Negation (-)**: Negates a value.
## Assignment Operators
**Assignment (=)**: Assigns a value to a variable.
**Addition Assignment (+=)**: Adds and assigns.
**Subtraction Assignment (-=)**: Subtracts and assigns.
**Multiplication Assignment (*=)**: Multiplies and assigns.
**Division Assignment (/=)**: Divides and assigns.
**Modulus Assignment (%=)**: Performs modulus and assigns.
**Exponentiation Assignment (**=)**: Performs exponentiation and assigns.
**Logical AND Assignment (&&=)**: Assigns if the left-hand side is truthy.
**Logical OR Assignment (||=)**: Assigns if the left-hand side is falsy.
**Nullish Coalescing Assignment (??=)**: Assigns if the left-hand side is null or undefined.
## Comparison Operators
**Equal (==)**: Checks if two values are equal (loose equality).
**Not Equal (!=)**: Checks if two values are not equal.
**Strict Equal (===)**: Checks if two values are equal (strict equality).
**Strict Not Equal (!==)**: Checks if two values are not equal (strict inequality).
**Greater Than (>)**: Checks if the left value is greater than the right.
**Less Than (<)**: Checks if the left value is less than the right.
**Greater Than or Equal (>=)**: Checks if the left value is greater than or equal to the right.
**Less Than or Equal (<=)**: Checks if the left value is less than or equal to the right.
## Logical Operators
**Logical AND (&&)**: Returns true if both operands are truthy.
**Logical OR (||)**: Returns true if at least one operand is truthy.
**Logical NOT (!)**: Negates the truthiness of a value.
## Bitwise Operators
**Bitwise AND (&)**: Performs a bitwise AND operation.
**Bitwise OR (|)**: Performs a bitwise OR operation.
**Bitwise XOR (^)**: Performs a bitwise XOR operation.
**Bitwise NOT (~)**: Inverts the bits of a number.
**Left Shift (<<)**: Shifts bits to the left.
**Right Shift (>>)**: Shifts bits to the right (sign-propagating).
**Unsigned Right Shift (>>>)**: Shifts bits to the right (zero-fill).
## Conditional Ternary Operator
# Data types
## number
Numeric values (integers, floats)
Example: ```42`, `3.14```
## string
textual data
example ``"hello","world``
## boolean
logical values(`true`or `false`)
example : ``true,false``
## undefined
unassigned variable
expample: ``let x; // undefined``
## null
International absence of value
example: ``let x = null;``
## biginit
Large integers
example : ``let x = 9007199254740991n;``
## Symble
Unique and immutable value
example: ``let x = Symbol('foo');``
## object
collection of key-value pairs
example: ``let x = { foo: 'bar' };``
## array
ordered collection of values
example: ``let x = [1, 2, 3];``
## function
Executable code block
example: ``function add(a, b) { return a + b; }``
## Date
Specific moment in time
example: ``let x = new Date('2022-01-01T00:00:)``
## RegExp
Regular expression for pattern matching
example: ``/abc/``
## NaN
Not a number
example: ``let x = NaN;``
## infinity
Number too large to handle
example: ``1 / 0``
## Negative infinity
Number too small (negative) to handle
example: ``-1 / 0``
