Types in Typescripts:

In typescript we have to specify the type of each identifier ( variables), so that only actions for that particular type that is available is allowed to be called. This makes the code more safer and bug free

For example, if you say a variable “name” is of type “string” then you can call toUpperCase method , and it shows the autocomplete suggestions . You cannot call any other methods like toFixed() , toString() etc as it is available only for numbers .

You cannot also assign number or anything else to it as we already defined it as string. ( YES IN JAVASCRIPT YOU CAN ASSIGN WHAT EVER YOU WANT!!! I LOVED THE LANGUAGE FOR THAT REASON)

Now lets see what are different types available :
