映射一个数组以创建一个新的对数组 [英] Map an array to create a new array of pairs

问题描述

我有两个单独的数组，我正在尝试创建一个将值分组在一起的新的嵌套数组.

I have two separate arrays and I'm trying to create a new nested array that has values grouped together.

我可以使用map()方法并配对map方法中的每个项目吗?

Can I use the map() method and pair each item inside the map method?

这里有一个类似的问题:映射数组数组

There is a similar question here: Map an array of arrays

但是，他的上下文有所不同，因为我没有嵌套数组.

However, he context is different because I don't have a nested array to begin with.

   var letters = [a, b, c];
   var numbers = [1, 2, 3];

   var lettersAndNumbers = letters.map((letter) => {
       numbers.forEach((number) => {
          return letter, number;
       );
    });
    
    // lettersAndNumbers = [[a, 1], [b, 2], [c, 3]]

感谢您提供任何提示，提示或解决方案！

Thank you for any tips, hints, or solutions!

推荐答案

为此，请使用以下

var letters = ['a','b','c'];
var numbers = [1, 2, 3];
var letterAndNumbers = letters.map((letter,index) => {
       return [letter,numbers[index]];
})

如果您打印它，您将收到以下输出

And if you print it, you will receive the following output

console.log(letterAndNumbers)
[ [ 'a', 1 ], [ 'b', 2 ], [ 'c', 3 ] ]
