🔢 Arithmetic Operators

Operation	C++	JavaScript	Notes
Addition	+	+	JS + also used for string concatenation
Subtraction	-	-
Multiplication	*	*
Division	/	/	In JS, division of integers can produce floats
Modulus	%	%
Exponentiation	—	**	JS only
Increment	++	++	Pre/post
Decrement	--	--	Pre/post

📝 Assignment Operators

Operation	C++	JavaScript	Notes
Assignment	=	=
Add & assign	+=	+=
Subtract & assign	-=	-=
Multiply & assign	*=	*=
Divide & assign	/=	/=
Modulo & assign	%=	%=
Exponent & assign	—	**=	JS only
Bitwise & assign	&=, etc.	&=, etc.	Both support

🔍 Comparison Operators

Operation	C++	JavaScript	Notes
Equal to	==	== (loose) / === (strict)	JS === also checks type
Not equal to	!=	!= (loose) / !== (strict)	Same as above
Greater than	>	>
Less than	<	<
Greater or equal	>=	>=
Less or equal	<=	<=

Operation	C++	JavaScript	Notes
AND	&	&
OR	|	|
XOR	^	^
NOT	~	~
Left Shift	<<	<<
Right Shift	>>	>> (arith) / >>> (logical)	JS adds logical shift >>>

🧪 Special Operators

Operation	C++	JavaScript	Notes
Ternary	?:	?:	Same syntax
Type checking	typeid, dynamic_cast	typeof, instanceof	Different mechanisms
Member access	. / ->	. / []	JS uses [] for dynamic keys
Scope resolution	::	—	C++ only
new operator	new	new	JS also uses class syntax
delete operator	delete	delete	In C++: memory; in JS: object property
Comma operator	,	,	Rarely used in JS
sizeof	sizeof	—	C++ only
Optional chaining	—	?.	JS only
