Operators in JavaScript

operator to operate on one or more variables or values (operands) and return a new value

Depending on the operation performed, the operators can be divided into the following categories:

(1) Arithmetic operators

(2) Comparison operators

Operator	Speak clearly	Show Example
==	Equals. Returns true if the two operands are equal.	A = = B
!=	Not equal to. Returns true if the two operands are not equal.	Var2! = 5
>	Greater than. Returns true if the left operand is greater than the right operand.	Var1 > Var2
<	Less than. Returns true if the left operand is less than the right operand.	Var2 < var1
<=	is less than or equal to. Returns true if the left operand is less than or equal to the operand to the right.	VAR2 <= 4 Var2 <= var1
>=	Greater than or equal. Returns true if the left operand is greater than or equal to the right operand.	VAR1 >= 5 Var1 >= var2

(3) Logical operators

Operator	Value	Speak clearly
and (&&)	Expr1 && EXPR2	It is only when expr1 and expr2 are true that they return true. Otherwise, returns false.
or (| |)	Expr1 | | Expr2	Returns true if one of the expressions is true, or two expressions are true. Otherwise, returns false.
Non - (!)	!expr	If the expression is true, False is returned. If False, returns TRUE.
