反应：创建和使用动态变量

Question

我有一个列表/数组cities = ["Bangalore", "Delhi", "Hyderabad", "Mumbai", "Chennai"]。我需要[city]Weather，[city]Temperature等动态变量。例如：我还需要BangaloreWeather，DelhiWeather，HyderabadWeather，MumbaiWeather，ChennaiWeather以及类似的温度指标。

我尝试使用 1）${city}Weather，但出现错误，因为“复杂的绑定模式需要初始化值”， 2）city+"Weather"     请帮助我解决问题。谢谢！

Answer 1

使用ES6，这可能有帮助？

const outcome =  ["Bangalore", "Delhi", "Hyderabad", "Mumbai", "Chennai"].reduce((accumulator, currentValue) => {
  accumulator[currentValue+"Weather"] = Math.random();
  return accumulator;
},{});

OUTPUT: 
{
  "BangaloreWeather": 0.7831037919683015,
  "DelhiWeather": 0.03695139822965743,
  "HyderabadWeather": 0.10986926586742629,
  "MumbaiWeather": 0.676334213130112,
  "ChennaiWeather": 0.9095092973413457
