TypeScript is a programming language with a lot to offer. It provides a robust type system that supports class-based object oriented programming. The language also has a strong type checking mechanism that ensures that your code is well-behaved. Aside from the standard types (string, int, float, boolean, and numeric), you can add types to functions and properties. This can help you to create more readable and maintainable code. In addition, the JavaScript compiler can convert TypeScript code into plain-old JavaScript. You can import and export TypeScript modules, too.

The best part is, TypeScript is free to use. It requires a compiler and an editor to get started. Once installed, you can start writing TypeScript code. However, you should be aware of some of the pitfalls that can result from using TypeScript. For example, you can run into code conflicts when you try to access variables in other files. To avoid these pitfalls, refer to the relevant resources.

One of the features of TypeScript is that it makes it easy to write functional programs that can be reused across the board. For instance, you can make the same Student object share the same methods and properties as the Person class. And, while you are at it, you can extend the student class with additional parameters.

Another feature is that you can use the same constructor to call up any number of nested methods. This is especially useful for refactoring. For example, if you have a Student class that you use to manage students, you can have the same Student objects access the same person methods and properties. If you are developing a large application, this can help you to simplify your codebase and keep you on track.

Other notable features include support for private and protected access modifiers, the ability to export and import module data, and a strong type system. These features help you to write more readable code that is easier to understand. There are many types and properties to choose from, and you can add types to variables and functions for a more modular approach to software development.

The 'let' keyword is similar to the var command. Only difference is that you must declare the variable within a block. That's not to say that you can't declare it outside the block. On the other hand, you will definitely get an error if you attempt to do the same thing with a const.

The biggest drawback to using TypeScript is that you can't run it on your browser directly. You can however, translate the ES6 style code to TypeScript or even translate TypeScript to ES6. But, if you are a JavaScript aficionado, you can go straight to the source with ZXing (Zebra Crossing). ZXing is a multi-format barcode image processing library that was ported to TypeScript from Java. Here's a link to the library's home page for more details.

Of course, if you really want to take the plunge, you should consider investing in a TypeScript IDE. While this can improve your workflow, it's not required.
