Simple Command Line Calculator

Develop a simple command line calculator using TypeScipt, Node.js and Inquirer.
Create a GitHub repository for the project and submit its URL in the project submission form.

Step 1 — Setting Up the Project

First, open your terminal window and create a new project directory:

    mkdir project_calculator

Then, navigate to this directory:

    cd project_calculator

To start adding prompts to your Node.js scripts, you will need to install the inquirer package:

    npm install ts-node typescript @types/inquirer --save-dev

inside actual dependenncies we need to install package:

    npm install inquirer

open your terminal window and create a new directory:

    mkdir src

go inside this directory with following command and crreate index.ts file inside it:

    cd src

add following lines into package.json file:

 
"scripts": {
    "start": "ts-node --esm ./src/index.ts",
    "build": "tsc.cmd ./src/index.ts"
  },

add following lines into package.json file:

 
"type": "module"

run following at project root directory:

 tsc --init

change following inside tsconfig.json file:

 
{
  "compilerOptions": {
    "target": "es6",
    "module": "ES6",
   ...
}

run following code at project root directory to execute node file or project file:

 npm start or yarn start

you are now 'good to go', make logic of your first calculator inside index.ts file in your desired IDE:

if you have cloned this project just run following command:

 npm intall or yarn add

to execute prewritten code inside index.tx run following command:

 npm start or yarn start

after running above mentioned command list of four option will displayed on your cli:
