很变扭是正常的，哈哈，如果从C语言语系(Java, C#, python)走到纯函数式比如clojure, haskell，那更...
which means that any declarations (variable or function) in that code will now be tied to the scope of the new wrapping function, rather than the previously enclosing scope. In other words, you can "hide" variables and functions by enclosing them in the scope of a function. ...
In JavaScript we have Function Scope and Lexical Scope. FunctionScopemeans that any variable which is defined within a function is visible within thatentire function. Block Scope, in which a variable scope is limited by the block a variable is declared in. A block is usual{curly brace} or l...

Use theFunction visibilityparameter for theTriggerblock within aSimulink Functionblock to set the function visibility to eitherscoped,global, orport. For a port-scoped function, specify the name of the port in theScope to portfield. Summary of Simulink Function Block Visibility and Access ...

If the base class function isn't declared asvirtual, then the derived class function is said tohideit. Both overriding and hiding are distinct from overloading. Block scope is strictly observed. A function declared in file scope isn't in the same scope as a function declared locally. If ...
