Definition (Code Smells) Code smells are common code anti-patterns which could and should be refactored.

This doc is summarized from Martin Flower's book Refactoring (the 2nd Edition).

Refactoring is all about Change

• You may inverse previous refactorings as software grows
• You may change names of a function/parameter/varible/... as you learn

How to use this doc

Go to a section of code smell, and the refactoring techniques to that smell are written in Pascal Case under the Solution section. Refer to the book's catalog to get detailed examples and explainations for each refactoring technique.

Why I hate TypeScript

Warning: These views are highly oppinated and might have some slightly incorrect facts. My experience with typescript was about 2 weeks in Node and a week in angular2.

Not Standard

TypeScript is implementing their own take on JavaScript. Some of the things they are writing will likely never make it in an official ES* spec either.

Technologies that have competing spec / community driven development have a history of failing; take: Flash, SilverLight, CoffeeScript, the list goes on. If you have a large code base, picking TypeScript is something your going to be living with for a long time. I can take a bet in 3 years JavaScript will still be around without a doubt.

Its also worth noting that they have built some things like module system and as soon as the spec came out they ditched it and started using that. Have fun updating!
