如何计算日期列与筛选表达式之间的日期差异

// 假设日期列的名称为"date"，筛选表达式为"date >= '2022-01-01'"
const dateColumn = [/* 日期列的数据 */];
const filterExpression = "date >= '2022-01-01'";

// 提取日期
const filterDate = new Date(filterExpression.substring(filterExpression.indexOf("'") + 1, filterExpression.lastIndexOf("'")));
const dateDifferences = [];

// 计算日期差异
for (const date of dateColumn) {
  const currentDate = new Date(date);
  const difference = Math.floor((currentDate - filterDate) / (1000 * 60 * 60 * 24)); // 计算天数差
  dateDifferences.push(difference);
}

console.log(dateDifferences); // 输出日期差异的数组
