问如何从2个数组中获取值并将其转换为新数组中的1个值？

EN

const result = interfaceTitles.map((_, i) => {
    return interfaceAmounts[i] + " " + interfaceTitles[i];
});

const array1 = [1, 4, 9, 16];
const array2 = ['a','b','c','d'];
// pass a function to map
// care in js we can use the + to concat string
// map will iterate over each element of array1
// x will be the current element of array1
// index will be the index of the current element,
// used to get the corresponding element in array2
const map1 = array1.map((x,index) => x+array2[index]);

console.log(map1);
// expected output: > Array ["1a", "4b", "9c", "16d"]
