What Is TypeScript?
|Error identification||Errors can be found and corrected during compile time.||Errors can be found only during run-time as it is an interpreted language.|
|Optional parameters in functions||Possible||Possible|
|Project scale||Large-scale. For complex apps with global development teams, TypeScript helps truncate the time of development and make the workflows more effective.||Small-scale. With clear and accurate structure, the language is perfect for compact simple apps.|
|Community||The TypeScript user community is still growing.||There is an established large community of developers.|
|Well-known clients||Slack, Accenture, Typeform, etc.||PayPal, Netflix, Uber, etc.|
Advantages and Disadvantages of Using TypeScript

- Preciseness. TypeScript allows for precise defining via typing. This feature ensures that everything stays as specified by developers.
- Type annotations. This feature ensures a convenient way to express unequivocally the type to be used.
- Type inference. Thanks to this characteristic, TypeScript developers don’t need to provide types when the compiler can find them without outside help.
- Structural typing. This is an essential feature for software engineers who are concerned about the actual structure that they use. The reliance on definite structure also facilitates the increased safety of TypeScript.
- More effective team efforts. The advantage of TypeScript is that it allows developers to focus solely on their own work without having to rely on their teammates. Thanks to the clearly defined data structures and type annotations, it is significantly easier to understand developers’ decisions and introduce new members to the team.
- High performance. TypeScript makes the development of individual engineers more effective, which leads to improved performance of the entire project team.
- Identifying errors. Compilation errors are revealed as soon as possible to prevent their further negative effects. TypeScript notifies software engineers once it identifies errors. This also facilitates a fast refactoring process, useful when the team has to handle ginormous volumes of code.
- Easy to read. It is easy to grasp the intention of software engineers who initially created the code, which is particularly advantageous for geographically dispersed teams working on the same project. The easily comprehensible coding thus makes collaboration more effective.
- Quick updates. To keep the TypeScript code maintainable, regular upgrading is necessary. With TypeScript, it is easy to update or refactor apps.
- Object-oriented programming. Thanks to the support of OOP concepts, TypeScript software engineers can build well-structured code that is easy to scale and maintain. This is particularly handy as projects become bigger and more complex.
- Longer time for compilation. As a rule, it is more time-consuming for TypeScript to carry out compilation.
- Not the best choice for small-scale projects. TypeScript shows its best characteristics for large-scale, complex projects with sophisticated heavy-load architecture.
- False sense of safety. TypeScript can check types and notify developers when there are errors in the coding. But do not let these functionalities delude you into thinking that everything written in TypeScript is flawless, as in reality it is not.
In IT since 1993, SaM Solutions offers professional custom software development services to clients across all industries.
- Popular. Every popular browser supports JS, and it is used by many large companies, including such tech giants as Meta, eBay, NASA, etc.
- Concise code. Thanks to the compact coding, JS can improve the functioning of web pages and apps.
- Error discovery during run-time. Unlike with TypeScript, it is impossible to discover errors at an early stage.
