function getRandomFromSection(low, high) {

  return Math.floor(RANDOM * RANGE) + low
}

Page({
  build() {
    const isVertical = true
    hmUI.setScrollView(true, px(480), 20, isVertical)

    const numArr = Array.from({ length: 20 }).map((_, index) => index)

    numArr.forEach((num) => {
      const backgroundColor = Array.from({ length: 6 }).reduce((prev, curr) => {
        const random = getRandomFromSection(0, 15)
        return prev + randomArr[random]
      }, '0x')

      hmUI.createWidget(hmUI.widget.FILL_RECT, {
        x: 0,
        y: px(480) * num,
        w: px(480),
        h: px(480),
        color: Number(backgroundColor)
      })

      const text = hmUI.createWidget(hmUI.widget.TEXT, {
        x: px(96),
