Packages & imports
Every Go file starts with a package declaration. Pick the
line that declares this file as belonging to the main
package — the convention for an executable's entry-point file.
TypeScript doesn't have a package declaration concept
(modules are file-based); Go's package line is mandatory
and is the first non-comment line in every file.

About this theme
Every file declares a package: package foo. Names starting with a capital letter are exported; lowercase are package-private. This rule is mechanical and pervasive; once you internalise it, you stop needing to look at export keywords because there aren't any. Imports go in a single import (...) block.
