Write a program to calculate salary in TypeScript

0 0 2 minutes read

In this article, we will understand how we could create a basic Salary Calculator in TypeScript by using simple mathematical logics and operators (like divide(“/”) or multiply (“*”) or addition (“+”)).

Syntax: Following is the syntax of enums:

enum enums_name {
    .......
}

Syntax: Following is the class declaration

class class_name {
    constructor () {
        .....
    }
    // Methods and variables.....
}

Following are the examples which show enums and class output on execution over the console.

Example 1: In this example, we will simply create enum and class and their randomly passed results.

Javascript

enum fruits_name { 
  APPLE = 'Apple', 
  MANGO = 'Mango', 
  GRAPES = 'Grapes'
} 
  
console.log('Enums Output : '); 
console.log(fruits_name); 
class Person { 
  name : string; 
  
  constructor (name : string) { 
    this.name = name; 
  } 
  
  displayName () : void { 
    console.log(`Name of a Person is : ${  this.name}`); 
  } 
} 
  
const person = new Person('zambiatek'); 
person.displayName();

Output:

Enums Output : 
{ APPLE: 'Apple', MANGO: 'Mango', GRAPES: 'Grapes' }
Name of a Person is : zambiatek

Now that we have understood in detail about enums and classes let us dive into our task of creating a basic Salary Calculator through the following example.

Example 2: In this example, we will create a basic salary calculator, in which the user will pass a total salary amount and further our logic will separate Basic Salary, Medical amount, House Rent amount, and Conveyance amount and displays the result over the console.

Javascript

enum SalaryDivision { 
  
    // Following values could be considered in % 
    Basic = 50, 
    HouseRent = 30, 
    Medical = 10, 
    Conveyance = 10 
} 
  
class SalaryCalculator { 
    GrossSalary : number; 
      
    constructor(GrossSalary : number) { 
        this.GrossSalary = GrossSalary; 
    } 
      
    displaySalary() : void { 
        let BasicSalary : number = (this.GrossSalary  
            * SalaryDivision.Basic) / 100; 
        let HouseRent : number = (this.GrossSalary  
            * SalaryDivision.HouseRent) / 100; 
        let Medical : number = (this.GrossSalary  
            * SalaryDivision.Medical) / 100; 
        let Conveyance : number = (this.GrossSalary  
            * SalaryDivision.Conveyance) / 100; 
        console.log("Basic Salary : " + BasicSalary); 
        console.log("HouseRent : " + HouseRent); 
        console.log("Medical : " + Medical); 
        console.log("Conveyance : " + Conveyance); 
    } 
} 
  
let salary1 = new SalaryCalculator(1000000); 
let salary2 = new SalaryCalculator(50000000); 
  
salary1.displaySalary(); 
salary2.displaySalary();

Output:

Basic Salary : 500000
HouseRent : 300000
Medical : 100000
Conveyance : 100000
Basic Salary : 25000000
HouseRent : 15000000
Medical : 5000000
Conveyance : 5000000
