怎么根据日K线数据算出出周线 月线 半年线 年线 季线数据，给出具体javascript 代码

以下是一个利用 JavaScript 对日K线数据进行重采样以计算周线、月线、季线、半年线和年线的示例代码：

// 将日K线数据按时间升序排列
data.sort((a, b) => a.timestamp - b.timestamp);

// 计算周线
const weekData = [];
let weekStart = data[0];
let weekEnd = data[0];
let weekHigh = data[0].high;
let weekLow = data[0].low;
let weekVolume = 0;
for (let i = 1; i < data.length; i++) {
  const current = data[i];
  if (new Date(current.timestamp).getDay() === 1) {  // 如果当前日期是周一
    weekEnd = current;
    weekHigh = Math.max(weekHigh, current.high);
    weekLow = Math.min(weekLow, current.low);
    weekVolume += current.volume;
    weekData.push({
      timestamp: weekEnd.timestamp,
      open: weekStart.open,
      close: weekEnd.close,
      high: weekHigh,
      low: weekLow,
      volume: weekVolume
    });
    weekStart = current;
    weekEnd = current;
    weekHigh = current.high;
    weekLow = current.low;
    weekVolume = current.volume;
  } else {
    weekEnd = current;
    weekHigh = Math.max(weekHigh, current.high);
    weekLow = Math.min(weekLow, current.low);
    weekVolume += current.volume;
  }
}

// 计算月线
const monthData = [];
let monthStart = data[0];
let monthEnd = data[0];
let monthHigh = data[0].high;
let monthLow = data[0].low;
let monthVolume = 0;
for (let i = 1; i < data.length; i++) {
  const current = data[i];
  if (new Date(current.timestamp).getMonth() !== new Date(monthEnd.timestamp).getMonth()) {  // 如果当前日期所在月份与上个周期不同
    monthEnd = current;
    monthHigh = Math.max(monthHigh, current.high);
    monthLow = Math.min(monthLow, current.low);
    monthVolume += current.volume;
    monthData.push({
      timestamp: monthEnd.timestamp,
      open: monthStart.open,
      close: monthEnd.close,
      high: monthHigh,
      low: monthLow,
      volume: monthVolume
    });
    monthStart = current;
    monthEnd = current;
    monthHigh = current.high;
    monthLow = current.low;
    monthVolume = current.volume;
  } else {
    monthEnd = current;
    monthHigh = Math.max(monthHigh, current.high);
    monthLow = Math.min(monthLow, current.low);
    monthVolume += current.volume;
  }
}

// 计算季线
const quarterData = [];
let quarterStart = data[0];
let quarterEnd = data[0];
let quarterHigh = data[0].high;
let quarterLow = data[0].low;
let quarterVolume = 0;
for (let i = 1; i < data.length; i++) {
  const current = data[i];
  if (new Date(current.timestamp).getMonth() % 3 !== new Date(quarterEnd.timestamp).getMonth() % 3) {  // 如果当前日期所在季度与上个周期不同
    quarterEnd = current;
    quarterHigh = Math.max(quarterHigh, current.high);
    quarterLow = Math.min(quarterLow, current.low);
    quarterVolume += current.volume;
    quarterData.push({
      timestamp: quarterEnd.timestamp,
      open: quarterStart.open,
      close: quarterEnd.close,
      high: quarterHigh,
      low: quarterLow,
      volume: quarterVolume
    });
    quarterStart = current;
    quarterEnd = current;
    quarterHigh = current.high;
    quarterLow = current.low;
    quarterVolume = current.volume;
  } else {
    quarterEnd = current;
    quarterHigh = Math.max(quarterHigh, current.high);
    quarterLow = Math.min(quarterLow, current.low);
    quarterVolume += current.volume;
  }
}

// 计算半年线
const halfYearData = [];
let halfYearStart = data[0];
let halfYearEnd = data[0];
let halfYearHigh = data[0].high;
let halfYearLow = data[0].low;
let halfYearVolume = 0;
for (let i = 1; i < data.length; i++) {
  const current = data[i];
  if (new Date(current.timestamp).getMonth() % 6 !== new Date(halfYearEnd.timestamp).getMonth() % 6) {  // 如果当前日期所在半年与上个周期不同
    halfYearEnd = current;
    halfYearHigh = Math.max(halfYearHigh, current.high);
    halfYearLow = Math.min(halfYearLow, current.low);
    halfYearVolume += current.volume;
    halfYearData.push({
      timestamp: halfYearEnd.timestamp,
      open: halfYearStart.open,
      close: halfYearEnd.close,
      high: halfYearHigh,
      low: halfYearLow,
      volume: halfYearVolume
    });
    halfYearStart = current;
    halfYearEnd = current;
    halfYearHigh = current.high;
    halfYearLow = current.low;
    halfYearVolume = current.volume;
  } else {
    halfYearEnd = current;
    halfYearHigh = Math.max(halfYearHigh, current.high);
    halfYearLow = Math.min(halfYearLow, current.low);
    halfYearVolume += current.volume;
  }
}

// 计算年线
const yearData = [];
let yearStart = data[0];
let yearEnd = data[0];
let yearHigh = data[0].high;
let yearLow = data[0].low;
let yearVolume = 0;
for (let i = 1; i < data.length; i++) {
  const current = data[i];
  if (new Date(current.timestamp).getFullYear() !== new Date(yearEnd.timestamp).getFullYear()) {  // 如果当前日期所在年份与上个周期不同
    yearEnd = current;
    yearHigh = Math.max(yearHigh, current.high);
    yearLow = Math.min(yearLow, current.low);
    yearVolume += current.volume;
    yearData.push({
      timestamp: yearEnd.timestamp,
      open: yearStart.open,
      close: yearEnd.close,
      high: yearHigh,
      low: yearLow,
      volume: yearVolume
    });
    yearStart = current;
    yearEnd = current;
    yearHigh = current.high;
    yearLow = current.low;
    yearVolume = current.volume;
  } else {
    yearEnd = current;
    yearHigh = Math.max(yearHigh, current.high);
    yearLow = Math.min(yearLow, current.low);
    yearVolume += current.volume;
  }
}

以上代码中，假设 `data` 是按时间升序排列的日K线数据数组，每个元素包含以下属性：`timestamp`（时间戳）、`open`（开盘价）、`close`（收盘价）、`high`（最高价）、`low`（最低价）和 `volume`（成交量）。代码中的五个循环分别计算了周线、月线、季线、半年线和年线的K线数据，结果分别存储在 `weekData`、`monthData`、`quarterData`、`halfYearData` 和 `yearData` 数组中。
