Bigger apps take longer to transmit and are slower to load.

JiT编译导致运行期间的性能损耗。
|
||||
由于需要在浏览器中的这个编译过程,视图需要花更长时间才能渲染出来。

由于需要在浏览器中执行这个编译过程,视图需要花更长时间才能渲染出来。
|

由于应用包含了Angular编译器以及大量实际上并不需要的库代码,所以文件体积也会更大。
|
||||
更大的应用需要更长的时间进行传输,加载也更慢。

Compilation can uncover many component-template binding errors.
|
||||
JiT compilation discovers them at runtime which is later than we'd like.

The **_Ahead-of-Time_ (AoT) compiler** can catch template errors early and improve performance
|
||||
by compiling at build time as you'll learn in this chapter.
