Operators:

Arithmetic Operators:
=====================
+	==> 	Addition	==> Binary
-	==> 	Subtraction	==> Binary
*	==> 	Multiplication	==> Binary
/	==>	Normal Division	==> Binary
%	==>	Modulo Division ==> Binary

Note:
=====
No integer data
No float data
we have only one representation: number

// Arithmetic Operations on only Integers

var a = 12
var b = 24
let c = 12.23;

console.log("Addition = "+(a+b));
console.log("Subtraction = "+(a-b));
console.log("Multiplication = "+(a*b));
/* 
normal Division ==> /
==> can return a quotient value

modulo division ==> %
==> can return the remainder
*/
console.log("Normal Division = "+(a/b));
console.log("Modulo Division = "+(a%b));

console.log("Addition = "+(a+c));
console.log("Subtraction = "+(a-c));
console.log("Multiplication = "+(a*c));
console.log("Normal Division = "+(a/c));
console.log("Modulo Division = "+(a%c));

================================================
Assignment Operator:
====================
==> =
==> for assigning the value to the identifier/expression etc.
ex: a = 10;

a = 12;

// c,b = 12,24;
// let b,c = 12,24;
let b,c;

b = 13;
c = 24;

// var p,q = (100,200);
p = 123;q = 131;

console.log(a);
console.log(b);
console.log(c);
console.log(p);
console.log(q);

================================================
Equality Operators:
====================
	== 	==> Equal Operator	==> binary
	!=	==> Not Equal Operator	==> Binary
		comparison
			return: Boolean values (true, false)
ex: 10 == 10 ==> true
10 != 10 ==> false

var a = 10;
let b = 10;

console.log(a == b);
console.log(a != b);
console.log(p = 1);
// q == 12

console.log(a = b);
=============================================================
Compound Operators:
===================
==> the operator combine with assignment operator is called as "compound operator".
+=, -=, *=, /=, %=
&&=, ||=, != 
&=, |=, ^= etc.

x = x + 10 ==> x += 10
x = x - 1 ==> x-=1

x = 100;    // by default this definition can understood as the 'x' is var type

console.log("x = "+x);
// x = x + 100;
x += 100;
console.log("x = "+x);
====================================================
String Concatenation Operator:
==============================
==> +
==> Concatenation ==> Joining of two or more strings into one string 
==> String ==> Group of characters
	can enclose with single quotes or double quotes.
ex: 'a' ==> string
'abc' ==> string
"a" ==> string
==> 'a' + 'b' ==> 'ab'

==> we can concate the number to the string or concat the string to the number.
ex: 73 + "Java"
"Java" + 73.123

var a = "JavaScript ";
var b = 'is Scripting Language';
let p = 'Java';
const q = 73; 

let c = a + b;
const r = p + q;

console.log(c);
console.log(r);
==========================================
Unary Plus and Unary Minus
===========================
Unary Plus ==> representing positive numbers
Unary Minus ==> representing negative numbers

a = 123;

console.log("The Value in Positive Nature = "+(+a));
console.log("The Value with negative sign = "+(-a));
=====================================================
Increment Operators:
====================
++
can increase the value by '1'.
==> can define in two ways:
	Pre-Increment Operator
	Post-Increment Operator
==> Unary Operators.

Pre-Increment Operator
======================
Syntax:
	++operand
1) can increase the value by '1'
2) assignment

var a = 101;
console.log("a = "+a);
++a;
console.log("a = "+a);
b = ++a;
console.log("a = "+a);  // 103
console.log("ab = "+b); // 103

Post-Incrementation:
===================
Syntax:
	operand++;
1) Assignment
2) Increase the value by '1'


b = ++a
b = a++

var a = 101

console.log("a = "+a);
a++;
console.log("a = "+a);
b = a++;
console.log("a = "+a);  // 103
console.log("b = "+b);  // 102

console.log("a = "+(a++));
console.log("a = "+a);
