有效JS表达式的角度模板语法错误

Question

这是我项目中模板的一个片段。

<footer>
  © {{ (new Date()).getUTCFullYear() }} Company
</footer>

Funfact是(new Date()).getUTCFullYear()是有效的JS语法。角度投掷错误的原因是什么？

这是堆栈跟踪/错误：

Error: Template parse errors:
Parser Error: Missing expected ) at column 7 in [
  © {{ (new Date()).getUTCFullYear() }} Company
] in ng:///AppModule/AppComponent.html@20:8 ("
</main>

<footer>[ERROR ->]
  © {{ (new Date()).getUTCFullYear() }} Company
</footer>
