[Solved] Array of objects containing objects to flat object array

by


this should work:

const all = [
    {
      "a": "Content A",
      "b": 
      {
        "1": "Content 1",
        "2": "Content 2"
      }
    },
    {
      "y": "Content Y",
      "x": 
      {
        "3": "Content 3",
        "4": "Content 4"
      }
    },
];
console.log(all.reduce((prev, el) =>{
    let curr = Object.entries(el);
let k1 = curr[0][0];
let k2 = curr[1][0];
    Object.entries(curr[1][1]).forEach((o => {
        
        let obj ={}
        obj[k1] = curr[0][1];
        obj[k2] = o[1];
        prev.push(obj);
    }))
    return prev;
},[]))
