How do I create object from multiple arrays?

So let’s say I have 2 arrays

keyword = ['test','123']
lang = ['en','fr']

From these two, I want to create an object from keyword that contains each lang. Like below

keywords = [
    {
      keyword: "test",
      lang: "en",
    },
    {
      keyword: "test",
      lang: "fr",
    },
    {
      keyword: "123",
      lang: "en",
    },
    {
      keyword: "123",
      lang: "fr",
    },
  ];

So in total I’ll have 4 objects cause each keyword will have their own lang. I’ve tried mapping but it’s just not possible once I have 1 keyword and 2 languages.

>Solution :

use a nested loop:

const keywords = [];
for (const k of keyword) {
  for (l of lang) {
    keywords.push({ keyword: k, lang: l });
  }
}
