JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js

Notes on hoisting

(I may be using incorrect terms below, please forgive me)

GraphQL allows us to define a UI-agnostic data model on the server using a graph schema that encodes the natural relationships within the data. To wire our model to data, we define resolvers in the schema that leverage our db's own query language (SQL, NoSQL, or Graph query language, etc) or in-memory objects to resolve client-defined, graph-oriented "queries" (or, more precisely, graph-oriented RPC) against our UI-agnostic data model.

With each components in the UI component tree declaring its own data dependencies, GraphQL/Relay creates a projection of the graph data model that maps to the UI component tree, thus allowing us to have a UI-agnostic data model on the server, while at once giving us and UI-specific projection of the data. The queries from GraphQL server to the database are composed in an efficient manner based on the aggregate data dependencies that are declared by each component in the UI component tree, thus eliminating redundant queries to the database.

Option 1: Command-line download extension as zip and extract

extension_id=jifpbeccnghkjeaalbbjmodiffmgedin   # change this ID
curl -L -o "$extension_id.zip" "https://clients2.google.com/service/update2/crx?response=redirect&os=mac&arch=x86-64&nacl_arch=x86-64&prod=chromecrx&prodchannel=unknown&prodversion=44.0.2403.130&x=id%3D$extension_id%26uc" 
unzip -d "$extension_id-source" "$extension_id.zip"

Thx to crxviewer for the magic download URL.
