What is TypeScript? The TypeScript programming language can be a great one to learn for certain coders. Learn more about it and what you need to do to develop this skill.
Let’s dive deeper into TypeScript and discuss whether it’s worth learning on your programming journey.
What is TypeScript?
It also provides developers with more debugging tools, making it easier to catch errors within massive code bases. However, it can be a little trickier for newer developers to learn and write, which we'll explore more later.
Features of TypeScript
What makes TypeScript a great language to learn? Here are just a few features of TypeScript that might be a huge advantage for your next coding project.
Static typing means that in a programming language like TypeScript, developers can declare the specific type (like numbers, strings, or booleans) of variables (containers that store data) and function inputs. The compiler, which checks the code before it runs, then verifies that the types match correctly. This helps catch mistakes and prevent errors that might occur when using the wrong type of data in different parts of the code.
Object-oriented Programming (OOP) Support
TypeScript supports Object-Oriented Programming (OOP) principles, allowing developers to define classes, objects, inheritance (the reusing of code), and encapsulation (bundling data).
With TypeScript, you don't always have to tell the program what type of data you're using because it can guess it by looking at the context and the initial values you give. For example, TypeScript knows that if you type in a number, it means a number.
Decorators are a language feature that allow developers to add metadata and modify the behavior of classes, properties, methods, or parameters at design time. They provide a way to extend and customize the functionality of existing code – without modifying its core implementation.
These allow developers to define functions, classes, or interfaces with placeholders for different types. This promotes code flexibility and type safety by providing a way to write generic algorithms and data structures that can be used with various data types.
Advantages of Using TypeScript
TypeScript is gaining popularity among developers. Here are just a few of its advantages, most of which concern cleaner, more efficient coding.
Better Error Detection
Better error detection allows developers to catch potential errors during the development phase. With static typing and type checking, TypeScript can identify type mismatches, undefined variables, and other common mistakes early on, leading to more reliable and bug-free code and more efficient coding.
Improved Integrated Development Environment (IDE) Support
This advantage enhances the development experience by providing features such as autocompletion, code navigation, and refactoring capabilities (rearranging things to make the code cleaner without changing what it does). IDEs can leverage TypeScript's static typing and type information to offer better suggestions for cleaner and more efficient code.
Easier Code Maintenance
Easier code maintenance makes the codebase more self-documenting. It improves code readability, aids in understanding dependencies (other pieces of code), and enables easier refactoring. Developers can modify and update code without introducing unintended errors.
With enhanced scalability, developers can handle larger and more complex codebases. Features like static typing, interfaces, and modules promote better code organization, reusability, and maintainability. This allows for smoother collaboration among teams to facilitate the growth and evolution of software projects.
Disadvantages of Using TypeScript
Despite its many benefits, TypeScript has some challenges. Here are some things to look out for when using TypeScript.
TypeScript introduces additional concepts and syntax, which may result in a steeper learning curve for developers who are new to the language or have limited experience with statically-typed languages.
The compilation step in TypeScript adds extra overhead to the development process. As the codebase grows, the compilation time can increase, which may impact your productivity and iteration speed.
Using TypeScript may require additional tools or software to be set up and configured correctly, which can make the development environment more complex.
TypeScript Tools and Resources
Here are some essential tools and resources that can help you navigate TypeScript.
The TypeScript Playground is an online interactive editor that allows developers to experiment with, write, and run TypeScript code directly in the browser. It provides a convenient environment for testing TypeScript features.

TypeScript Libraries and Frameworks
They also offer ready-to-use solutions for common tasks, such as handling HTTP requests.
How to Learn TypeScript
Learning TypeScript is just like learning any other programming language. Your current experience level with coding might change how you get started learning TypeScript.
