If you're not using typescript in your development process, you're doing it wrong. Here are 5 reasons why you should be using typescript.

1. Typescript is a typed language, which means that it can catch errors in your code as you type. This makes it much easier to find and fix errors, saving you time and frustration.

2. Typescript is based on javascript, so you already know how to use it. If you're already familiar with javascript, you'll be able to start using typescript with little or no learning curve.

3. Typescript offers many features that aren't available in javascript, such as type inference and generics. These features make your code more readable and easier to maintain.

4. Typescript is being developed by Microsoft, so it's sure to be around for a while. Microsoft is fully behind typescript and is committed to its development.

5. Typescript is open source, so it's free to use. There are no licensing fees or royalties to pay.

Currently, typescript is being used by many large companies, including Microsoft, Google, and Netflix.
