the concept of a project object model (POM), Maven can manage a project's
build, reporting and documentation from a central piece of information.

If you think you have found a bug, please file an issue in the [Maven Issue Tracker][jira].

关键特性:

* **快速**：可与 **NodeJS** 和 **Go** 并肩的极高性能（归功于 Starlette 和 Pydantic）。[最快的 Python web 框架之一](#_11)。

* **高效编码**：提高功能开发速度约 200％ 至 300％。*
* **更少 bug**：减少约 40％ 的人为（开发者）导致错误。*
* **智能**：极佳的编辑器支持。处处皆可<abbr title="也被称为自动完成、智能感知">自动补全</abbr>，减少调试时间。
* **简单**：设计的易于使用和学习，阅读文档的时间更短。
* **简短**：使代码重复最小化。通过不同的参数声明实现丰富功能。bug 更少。
* **健壮**：生产可用级别的代码。还有自动生成的交互式文档。
