Currently,I have finished the first 2 chapters.I found several downsides of the book:
1. web editor the author recommended is unfamous and in minority, seldom developers might use enide studio.As a result,its degbugging functionality is not applied to me and RESTClientTool is suitable for me.
my Suggestions:
a.use common middle-level editors,say,sublime or brackets or atom or visual studio code.
b.Also,the node debugging should involve node-inspector module or VSC debugging.
c.use the Postman( a chrome plugin) to replace RESTClientTool of the Enide studio.
2.function or variable name convention is not good.It would be more favorable that test_add should be changed to testAdd which uses camelCase name convention.
3.It would be less confused to use modules.exports compared with exports.
