angularangular-compiler

Does the Angular Compiler optimize string expressions?

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.

Solution

  • 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;
