HarmonyOS ArkTS有命名空间吗

namespace mynamespace{ 
 export function foo1(){ 
  console.log('testTAG','File1') 
 } 
}

namespace mynamespace{ 
 export function foo2(){ 
  console.log('testTAG','File2') 
 } 
} 
export default mynamespace

import mynamespace1 from '../file1' 
import mynamespace2 from '../file2' 
 
@Entry 
@Component 
struct Index { 
 @State message: string = 'Hello World'; 
 
 build() { 
  Row() { 
   Column() { 
    Text(this.message) 
     .fontSize(50) 
     .fontWeight(FontWeight.Bold) 
     .onClick(() => { 
      mynamespace1.foo1() 
      mynamespace2.foo2() 
     }) 
   } 
   .width('100%') 
  } 
  .height('100%') 
 } 
}
