M104	Warning	Name is already a function
M105	Warning	Var name is used before its declaration
M106	Warning	Name is already a var

M127	Warning	Expression statements should be assignments, calls or delete expressions only
M128	Error	A state cannot have the specified child item
M201	Hint	Place var declarations at the start of a function

M307	Warning	Use new only with functions that start with an uppercase letter
M308	Warning	Do not use Number as a constructor
M309	Hint	Use spaces around binary operators
M310	Warning	Unintentional empty block, use({}) for empty object literal
