Angular Compiler 是否优化了字符串表达式？

Question

I have the following code snippet:

"foo".length > 0 ? true : false;

Does the Angular compiler replace it just with true ?

tsc does not do; I tried it out.

Answer 1

That's the job of the minifier, noy the compiler.

For example Esbuild (a bundler used by angular) will do that for you:

echo '[1].length > 0 ? true : false' | esbuild --loader=ts --minify
> [1].length>0;
