Foreach when key is not a number

Issue

In my project i push a array into a table in firebase realtime database. Firebase generate a token and not a numeric id for each array:

{
    "-N2mToYDj-i8ToErmaUj": {
        "anzahl": 2,
        "groesse": 0.5,
        "name": "getraenk1",
        "preis": 5.5
    },
    "-N2mX3RPnDXxWMHMJScy": {
        "anzahl": 1,
        "groesse": "0.25",
        "name": "getraenk2",
        "preis": 2.2
    },
    "-N2mXBT8c7EKlIgyrU72": {
        "anzahl": 1,
        "groesse": "0.5",
        "name": "getraenk3",
        "preis": 3.4
    },
    "-N2mXZD1BoCslj81Lcya": {
        "anzahl": 1,
        "groesse": "1",
        "name": "getraenk4",
        "preis": 5.2
    "-N2m_g8GutpAFqsN4WsP": {
        "anzahl": 1,
        "groesse": "0.33",
        "name": "getraenk5",
        "preis": 3.2
    },
}

How can i work with each object when the key value is not numeric. ForEach() does not work for me.

Solution

Lets say your data stored in test object. you can use Object function in javascript to work with any object. For accessing all key you can try this:

Object.keys(test).map(key => { // key in here can be for example -N2mToYDj-i8ToErmaUj
    const data = test[key] // this is the full object that each key points to
/* 
   {
        "anzahl": 2,
        "groesse": 0.5,
        "name": "getraenk1",
        "preis": 5.5
    }
*/
})
