JavaScript/TypeScript中有没有一种方法可以在一个对象中添加两个数组并对它们进行排序?

问题描述：

我必须要数组:

countries = ["USA", "Spain", "Italy", "France", "Germany", "UK", "Iran", "Turkey", "Belgium", "Netherlands", "Canada", "Switzerland", "Brazil", "Russia", "Portugal", "Austria", "Israel", "Ireland", "Sweden", "India", "S. Korea", "Peru", "Chile", "Japan", "Ecuador", "Poland", "Romania", "Norway", "Denmark", "Australia", "Czechia", "Pakistan", "Saudi Arabia", "Philippines", "Mexico", "Malaysia", "Indonesia", "UAE", "Serbia", "Panama", "Qatar", "Ukraine"]

mortalityRates = ["4.17", "10.46", "12.97", "10.98", "2.49", "12.90", "6.25", "2.15", "13.36", "10.74", "3.34", "4.53", "5.70", "0.81", "3.25", "2.70", "0.99", "3.54", "9.03", "3.36", "2.10", "2.21", "1.16", "1.87", "4.67", "3.65", "5.10", "2.10", "4.59", "0.95", "2.63", "1.64", "1.36", "6.41", "6.62", "1.64", "9.49", "0.55", "2.11", "2.71", "0.20", "2.91"]

我的目的是在Charts.js上使用此数据.因此，我想合并数据并以某种方式按死亡率(从最大到最小)对它们进行排序.

My purpose is to use this data on charts.js. So, I want to merge the data and sort them, somehow, by the mortality rate (biggest to smallest).

答

为合并的对象创建一个数组，然后按死亡率对对象数组进行排序:

Create an array for the merged objects, then sort the array of objects by mortality rate:

const countries = ["USA", "Spain", "Italy", "France", "Germany", "UK", "Iran", "Turkey", "Belgium", "Netherlands", "Canada", "Switzerland", "Brazil", "Russia", "Portugal", "Austria", "Israel", "Ireland", "Sweden", "India", "S. Korea", "Peru", "Chile", "Japan", "Ecuador", "Poland", "Romania", "Norway", "Denmark", "Australia", "Czechia", "Pakistan", "Saudi Arabia", "Philippines", "Mexico", "Malaysia", "Indonesia", "UAE", "Serbia", "Panama", "Qatar", "Ukraine"]
const mortalityRates = ["4.17", "10.46", "12.97", "10.98", "2.49", "12.90", "6.25", "2.15", "13.36", "10.74", "3.34", "4.53", "5.70", "0.81", "3.25", "2.70", "0.99", "3.54", "9.03", "3.36", "2.10", "2.21", "1.16", "1.87", "4.67", "3.65", "5.10", "2.10", "4.59", "0.95", "2.63", "1.64", "1.36", "6.41", "6.62", "1.64", "9.49", "0.55", "2.11", "2.71", "0.20", "2.91"]
    
const merged = []
for (let i = 0; i < countries.length; i++) {
  merged.push({
    country: countries[i],
    rate: mortalityRates[i],
  })
}
merged.sort((a, b) => b.rate - a.rate)

console.log(merged)

还有一线:

const merged = countries
  .map((country, i) => ({ country, rate: mortalityRates[i]}))
  .sort((a, b) => b.rate - a.rate)
