What is TypeScript?
Key benefits of TypeScript and how to use them?
Optional static typing
TypeScript uses optional strong static typing. It is typical that during operation the variable changes only specific values, while the variable type does not change. The compiler warns developers about errors related to the type of variables. Thanks to this, the system can more effectively resist new errors and eliminate existing ones. Reducing the number of errors in turn contributes to speeding up the development.
Early spotted bugs
Programming language researchers have proven that TypeScript detects about 15 percent of errors at an early stage. The rapid elimination of a large part of the errors can significantly reduce developer time. Pushing code through the compiler, in turn, reduces the effort needed to maintain high-quality performance and test the system.
By adding strong types and other system elements that make the code more self-expressive, the intention of the coders who originally wrote the code becomes more understandable to an outside observer. This is incredibly convenient if you are working in a distributed team on the same project.
Any refactoring or update of an application requires that its codebase be reliable and maintainable. Otherwise, developers may have serious problems. TypeScript allows you to achieve this result in the shortest possible time.
In addition, a relatively large number of errors are detected automatically. For example, if you rename a function and then forget to change the name, TS will remind you of this. This simplifies and speeds up refactoring, which is especially useful when working with large parts of the codebase.
Cross-platform and cross-browser compatibility
The main disadvantages of TypeScript
Lack of static typing
The lack of true static typing is a fairly common TypeScript problem. Many developers complain about the lack of this feature. This is a serious disadvantage, the work on the elimination of which is one of the unsolved problems.
Adding an extra step – transpilation
TypeScript continues to improve. Developers get control over how the system works. It becomes more manageable and, as a consequence, better able to meet the challenges it faces.
