[javascript] How to use forEach in vueJs?

I have a response like below from an API call,

Now, I have to repeat the whole arrays inside the arrays. How do I do that in VueJS?

I have searched for using forEach.. nowhere I found forEach usage like key|value pair.

Can anyone help me on how to fetch the values from that arrays by using either forEach or any else(VueJS)?

Thanks & Regards,

You can also use .map() as:

var list=[];

response.data.message.map(function(value, key) {
     list.push(value);
   });
