javascript - 一起显示英里每小时和公里每小时？

Question

我想同时显示英里每小时和公里每小时。那可能吗？

如何实现公里每小时计算并一起显示？

function getMiles (knots) {

    var mph = (knots * 1.15078);
    var speed = Math.round(mph);


    if (speed < 50) {
        return speed + console.log('mhp ');
    }
    if (speed > 50) {
        return speed + console.log('mph , wind can be too strong today ');
    };
}getMiles()

Answer 1

您返回较早，添加 kph 并将其连接起来。

const wind = knots => {
  const miles = Math.round(knots * 1.15078)
  const kph = Math.round(knots * 1.852)

  return `${miles} mph / ${kph} kph ` + (
    miles > 50 ? 'wind can be too strong today' : ''
  )
}

console.log(wind(80))
