是否有更多的javascript方法来处理压缩两个数组而不是使用for循环？

Question

This code works as intended based on the problem I am supposed to solve. However, as I am new to JavaScript, I was curious if this is the proper way to handle zipping two arrays. I've already read a few examples using map which seem concise, but I am more curious if there is a generally agreed upon proper method in JavaScript to do this?

var faker = require("faker");

var products = Array.from({length:10}, () => faker.commerce.productName());
var prices = Array.from({length:10}, () => faker.commerce.price())

var strOut = "";
for(var i=0; i<10; i++){
    strOut += `${products[i]} - ${prices[i]} \n`
}

console.log('====================\n'+
'WELCOME TO MY SHOP!\n'+
'====================\n'+
`${strOut}`);

Answer 1

1) reduce :

const strOut = products.reduce(
  (result, product, index) => `${result} ${product} ${prices[index]}\n`,
  ''
);

2) map + join :

const strOut = products.map( 
   (product, index) => `${product} ${prices[index]}`
).join("\n");

second argument of map 's callback is the array index, you can use it for second array.
