var aCtor = a.constructor, bCtor = b.constructor; if (aCtor !== bCtor && !(_.isFunction(aCtor) && aCtor instanceof aCtor && _.isFunction(bCtor) && bCtor instanceof bCtor) && ('constructor' in a && 'constructor' in b)) { return false; } 這里為什么要這么判斷兩個對象是否相等？ 代碼來自underscore中的Equal函數(shù)這里的a，b待判斷的對象
underscore中對于對象相等判斷
