So you have objects with properties 0, 1, ... etc., which are not arrays? Nice. — kol

You could get a flat array with assigning the objects to an array.

const
    data = [{ 0: { a: 1, b: 2 }, 1: { c: 3, d: 4 } }, { 0: { e: 5, f: 6 }, 1: { g: 7, h: 8 } }],
    flat = data.flatMap(o => Object.assign([], o));

console.log(flat);

.as-console-wrapper { max-height: 100% !important; top: 0; }
