Operators.js

// In Javascript all the operators behavious is same as the Java Operators

// Arithmetic Operators

// plus operator
const a = 20;
const b = 30;
const c = a + b;

// Minus Operator
// Multiplication Operator
// Divide operators
// % Operators
// Post Increment
// Pre Incerement Operators
// Ternary operators
//  Logical operators

// Assign Ment Operator
//  == and  ===

// if you want to compare the value then  ==  operator will give true output if value are same

// Type coersion
// explicitly , implicitly

//dynamically converting one type into another type is called the type coersion

// explicit  => type casting => it is done by the developer

// conversion  => to string , to boolean  and to Number

// to string

// parseFloat
