Puedes usar un for :

Ejemplo:

 const cars = ["BMW", "Volvo", "Saab", "Ford", "Fiat", "Audi"]; let text = ""; for (let i = 0; i < cars.length; i++) { text += cars[i] + "<br>"; } document.getElementById("demo").innerHTML = text;

Está buscando Object.values para recuperar solo la parte de valor de su objeto.

Ejemplo:

 const object = { "20-01-22": ['a', 'b', 'c'], "21-01-22": ['b', 'c'], "22-01-22": ['d', 'f'] }; const arrays = Object.values(object) // => [['a', 'b', 'c'], ['b', 'c'], ['d', 'f']];
