如何破解.map功能

Question

如何打破.map功能？代码示例如下.我希望在索引达到5时打破外观,因为我只想将5个头像渲染到屏幕上.

<View style={{ flexDirection: 'row', marginTop: 20, marginLeft: 30  }}>
    {
      peopleGroup.map((people, i) => {
        if(i<5) {
          return (
            <Avatar
              key={people.id}
              width={30}
              position='absolute'
              containerStyle={{ transform: [{translate: [-28 + (28 * i), 0, 1 - (i * 0.1)]}] }}
              small
              rounded
              source={{uri: people.image}}
              activeOpacity={0.7}
              />
          )
        }else if(i===5) {
          return (
          <View key={i} style={{ transform: [{translate: [(25 * i), 9, 0]}]  }}>
            <Text>{peopleGroup.length}</Text>
          </View>
          )
        }
      }
      )
    }
</View>

Answer 1

Array.slice在映射之前使用.

peopleGroup
.slice(0, 5) // creates a copy of original, 5 items long
.map(...) // subsequent operations work on the copy
