TypeScript is a superset of JavaScript and has some vital advantages which make it profoundly used in Angular, React. Following are the key points that make TypeScript unique which includes but are not limited to 

1. Discretionary static typing(the key here is discretionary)
2. Intuitive Type Interface which allows programmers to get more code without typing 
3. Early access to ES6 and ES7 features even before support from various browsers

Now that we have discussed TypeScript and its benefits, let’s deep dive into TypeScript installation.

Step 4: If tsc command throws the error you can install the TypeScript with the following command 

npm install -g typescript

or

npm i typescript

-g describes the global installation, and i describes the local folder installation of TypeScript
Step 5: The above command will install the TypeScript
Step 6: Once installed you can check the correctness of installation by typing tsc in Command Prompt

Going further we will discuss our first program in TypeScript.
