关键字和保留字

具有特定用途的，目前全部关键字：

break do instanceof typeofcase else new varcatch finally return voidcontinue for switch whiledebugger function this withdefault if throwdelete in try let

有可能在将来被用作关键字——保留字

abstract enum int shortboolean export interface staticbyte extends long superchar final native synchronizedclass float package throwsconst goto private transientdebugger implements protected volatiledouble import public
