Javascript-operators

Javascript support different types of operators. They are:

• Arithmetic Operators
• Comparision Operators
• Logical (or Relational) Operators






• Assignment Operators
• Conditional (or ternary) Operators

—–>Arithmetic Operators

JavaScript supports arithmetic operators . A typical arithmetic operation operates on two numbers.

eg:
var x=100=50;
or
var x= a+b;(using variables)










Operator	Description
(+) Addition	Add two operands eg:A+B(A=10;B=30 will give 40)
(-)Subtraction	Subtracts the second operand from the first eg: A-B(A=10;B=30 will give -20)
(*) Multiplication	Multiply both operand eg:A*B(A=2;B=4 will give 8)
(/)Division	Divide the numerator by the denominator eg:A / B (A=20;B=10 will give 2)
( % )Modulus	Outputs the remainder of an integer division eg: B % A (A=10;B=20 will give 0)
(++) Increment	Increases an integer value by one eg: A++ (A=10 will give 11)
(–) Decrement	Decreases an integer value by one eg: A– (A=10; will give 9)






—->Comparision Operators

Javascript support comparison operator






Operator	Description
( = = )Equal	Checks if the value of two operands are equal or not. eg: A == B (A=10;B=20; is not true).
( != ) Not Equal	Checks if the value of two operands are equal or not, if the values are not equal, then the condition becomes true. eg: A != B (A=10;B=20 is true.)
( > ) Greater than	Checks if the value of the left operand is greater than the value of the right operand, if yes, then the condition becomes true. eg: A > B (A=10; B=20 is not true.)
( < ) Less than	Checks if the value of the left operand is less than the value of the right operand, if yes, then the condition becomes true. eg:A < B(A=10;B=20; is true)
( >= ) Greater than or Equal to	Checks if the value of the left operand is greater than or equal to the value of the right operand, if yes, then the condition becomes true. eg:A >= B (A=10;B=20 is not true)
( <= ) Less than or Equal to	Checks if the value of the left operand is less than or equal to the value of the right operand, if yes, then the condition becomes true. eg: A <= B (A=10; B=20 is true)

Logical (or Relational) Operators

Javascript also support different types of logical oprator.






Operator	Description
( && ) Logical AND	If both the operands are non-zero, then the condition becomes true. eg: A && B.
(||) Logical OR	If any of the two operands are non-zero, then the condition becomes true. eg: A || B.
( ! ) Logical NOT	Reverses the logical state of its operand. If a condition is true, then the Logical NOT operator will make it false. eg: ! (A && B).
