JavaScript, Iterate through object of arrays [duplicate]

I have an Object like this:

{
    1: [{'id':'1','value':'aa'}],
    2: [{'id':'2', 'value':'aa'}, {'id':'2','value':'bb'}],
    3: [{'id':'34', 'value':'cc'}]
}

How should I iterate that object? I'm very confused about it

I tried things like:

// object es my var 
Array.from(object).forEach(a => {
    console.log(a)
});

Array.prototype.forEach.call(object, child => {
    console.log(child)
});

With out success
