 ## Syntax vs. Semantics
 Just because something is *syntactically* correct doesn't mean it is *semantically* correct. Consider the following piece of TypeScript code which although *syntactically* valid is *semantically* wrong

 ## Processing Overview
 The following is a quick review of how these key parts of the TypeScript compiler compose:
 
-```code
+```
 SourceCode ~~ scanner ~~> Token Stream
 ```
 
-```code
+```
 Token Stream ~~ parser ~~> AST
 ```
 
-```code
+```
 AST ~~ binder ~~> Symbols
 ```
 `Symbol` is the primary building block of the TypeScript *semantic* system. As shown the symbols are created as a result of binding. Symbols connect declaration nodes in the AST to other declarations contributing to the same entity.
 
 Symbols + AST are what is used by the checker to *semantically* validate the source code

 AST + Symbols ~~ checker ~~> Type Validation
 ```
 
 Finally When a JS output is requested:
