Types of Operators in JavaScript

Types of Operators:

• Arithmetic Operator
• Boolean Operator
• Increment & Decrement Operator
• Comparison Operator
• Conditional Operator
• Logical Operator

Arithmetic Operator:

• Arithmetic operators are used basic mathematical operations.
• They usually have two operands and one operator.

Operators: + , - , * , / , % , **

(10 + 5); // 15 (Addition Operator)

(5 - 3); //2 (Subtraction Operator)

("10" + 5); // "105" (string + number → concatenation)
("10" - 5); // 5 (string converted to number automatically)

• JavaScript is a dynamically typed language, so it automatically converts numeric strings into numbers when needed.
• If you want to manually convert a string to an integer → use parseInt().

(10 * 2); // 20 (Multiplication Operator)
(10 / 2); // 5 (Division Operator)

(10 % 2); // 0 Modulus (remainder)
(2 ** 3); // 8 (2*2*2) (Exponentiation Operator)

Boolean Operator:

• Boolean has only two values:

• true or false.

• In boolean value True is 1.

• In boolean value False is 0.
  Example:

• true+1 =2

• false-2 =-2

Increment & Decrement Operator
PostIncrement:(i++)
It first assign the value and then increase.

Example:
i=5;
log(i++);//5(value )
log(i);//6 (increase)

Postdecrement:(i--)
It first assign the value and then decrease.

Example:
i=5;
log(i--);//5 (value )
(i--);//4 (decrease)

Preincrement:(i--)
It first increase the value and then assign.

Example:

i=5;
++i;
log(i);//6

Predecrement:(i--)
It first decrease the value and then assign.

** Example: **
i=5;
--i;
log(i);//4

Comparsion Operator
Compare both the value and return the boolean value true or false .

Example:

== Method

5==5 //true

"5"==5(In this case it return the true value because it check only the values not the datatypes)

=== Method

"5"=== 5 // false

"5"===5 (In this case it return the flase value because it check both the values and the datatypes)

Greaterthan Operator & lessthan Operator(>,<)

Example:
7>5//True
5<7//true

Greaterthan or equal to Operator & lessthan or equal to Operator(>=,<=)

Example:

5<=5//true

Logical Operator

OR ->||
AND ->&&
NOT ->!

OR(||) :

• If any one condition is true it return true.

Example:

5<5 || 4>2 // true (any one true it return true)
false true

AND(&&):

• It return true only when Both the condition are true.Otherwise it return flase.

Example:

5<5 && 4>2 // true (both condition are true then only return true otherwise false)
