如何在 JavaScript 中计算两个日期之间的分钟数？

给定两个日期，任务是使用 JavaScript 获取它们之间的分钟数。

方法：

• 初始化两个 Date 对象。
• 从新日期中减去旧日期。它将给出从 1970 年 1 月 1 日开始的毫秒数。
• 将毫秒转换为分钟。

示例 1：此示例使用当前日期和下一个 newYear 日期来获取日期的差异（以分钟为单位）。

            // Display the dates
            up.innerHTML = "Today's Date= "+ today.toLocaleDateString()
                + "<br> newYear's Date = " + newYear.toLocaleDateString();
              
            // Function to calculate difference
            // between two dates
            function GFG_Fun() {
                var dif = (newYear - today);
                var dif = Math.round((dif/1000)/60);
                down.innerHTML = "Minutes left = " + dif;
            }
