+## To Try
+
+* tsconfig file series practice
+  It seems that `esm5` and `esm2015` compiling result from typescript source
+  code could be directly used for the keys, [`module`](https://github.com/rollup/rollup/wiki/pkg.module)
+  and `es2015`,  in `package.json` file.
+
+  This practice could also be totally referenced in `rxjs` official repository,
+  where different tsconfig files are prepared for compiling target as `es5` and
+  `es2015`.
+
+  This attempt sounds that a little time would be cost without any apparent technical
+  barrier that need to spend time for inspecting and learning.
