 # Notes on _Douglas Crockford's_ Javascript the Good Parts :rocket:
+
+> These are _notes_ on the book `Javascript the Good Parts` which was published
+in **2008, before es6**. There have not been any revised editions of the book published at the time of writing,
+see http://www.github.com/dwyl/Javascript-the-Good-Parts-notes/issues/33 for the
+ongoing conversation on this.
+
 This book calls out the best parts of Javascript and tells you what to avoid (the 'bad parts').
-It's about making sure you **know the really important parts of the language** and **create good habits** instead of having to break bad ones down the line.

+The idea of these notes is to collect the excellent information from an already
+dense book  into note form, **translating these ideas into _'plain English'_**
+where possible and _adding explanations_ throughout where the book might not make
+things obvious as it assumes prior knowledge.
