Abstract
En 中文
The TypeScript programming language adds static types to JavaScript, which can be seen as a superset of JavaScript. As special infrastructure software, programming languages may also have bugs, preventing the correct source code from being executed correctly and reliably. To deeply understand the characteristics of historical bugs in the TypeScript programming language, this paper conducts an empirical study. The study involved the versions and features of programming language affected by bugs, the symptoms caused by bugs, the efforts to fix bugs, and the root causes of bugs. By analyzing 8814 bug reports and 7974 pull requests in the repository of TypeScript, our findings reveal that programming language features most severely affected by bugs are Name, Binding and Scope and data types. The most frequent symptoms include Behavior Error and Compile Error. The most common root causes are Missing Features, Wrong Control Flow, Data Type errors, and Processing errors, all of which could be categorized into Semantic errors. Our findings could reveal some characteristics of bugs in TypeScript, provide potential help to developers, testers, and maintainers of TypeScript to improve the quality of TypeScript, and provide a better programming experience for users of TypeScript.
