// assignment operator used to assign value to variables
let d = "string"
d += 1  //increment assignment operator
d -= 1  //decrement assignment 
d *= 2  //multiplication assignment
d /= 3  // division assignment
d **= 2  //exponential assignment




// Arithmetic operator is consists of 
// arithmetic operations on numbers

console.log("Addition ",5 + 7)
console.log("Subtraction ",6 - 3)
console.log("Multiplication ",7 * 1)
console.log("Division ",9 / 3)
console.log("Modulus ",9 % 2)
console.log("Exponential ",7**2)




// Comparison operator used to compare values
// and returns boolean values
console.log(6 == 4)    //equals or not
console.log(7 > 9)     //greater than
console.log(7 <= 9)     // less than/equal to,  and so on 





// Logical operator used to write logical functions
// also returns boolean value

8 && 8   // logical and,  returns true if both true else false
8 || 7   // logical or,  returns true if one of two is true
!true    // logical not, returns opposite value






// increment/decrement operator is used on variables to 
// increase/decrease thier value as postly or previously
let a = 6
console.log("default value ", a)
console.log("post increment/decrement shows changes on same line", a++)
console.log('after increase in previous line',a)
console.log("pre decrement/increment shows changes on same line", --a)
console.log("after decrease in previous line", a)





// Bitwise operators are used to do bitwise functions
// like:  &, |, ~, ^, <<, >>, >>>
