如果是这样,我不直接学习java或者c#就好了吗?(不考虑前端编程这个因素)
或者换句话说,typescript跟java在语法语义有什么不同吗?能给编程带来什么帮助吗?
带着这个疑问,翻了一下现有的资料,找到typescript官网的一段解释,觉得有点意思,翻出来,供大家参考。

Rethinking Types
These aspects describe a reified, nominal type system. The types we wrote in the code are present at runtime, and the types are related via their declarations, not their structures.
TypeScript provides a number of mechanisms to work with types in a set-theoretic way, and you’ll find them more intuitive if you think of types as sets.
简单讲,typescript将类型看做集合们。这个思想可以说总算回归到正义了。
其他的没有看懂,鸭子类型的实现似乎太宽泛了。
另外,由于编译过程中将类型信息抛弃了,造成运行时类型反射没法进行,不能不说是一个遗憾。
