如何将这两个数组合并为一个

Question

Could anyone please advice how to merge two arrays (same length) into one ? Thank you! The spread operator didnt work in that way..

let Array1 = [[A,B],[C,D]];
let Array2 = [1,2];

let Array3 = [...Array1, Array2];

Answer 1

Use a forEach loop

 var arr=[['A','B'],['C','D']]; var arr2 = [1,2]; arr.map((i,j)=>i.push(arr2[j])) console.log(arr)

Answer 2

Using .map() and .concat() you can combine the arrays.

Try the following:

 let Array1 = [['A','B'],['C','D']]; let Array2 = [1,2]; const result = Array1.map((e, i) => e.concat(Array2[i])); console.log(result);

I hope this helps!
