Read the list of Ids from nested JSON

I need to read the ids from nested loop using Javascript.

Input:

let data = [3,[{
"Id": 30,
"Name":"John"
},{
"Id": 33,
"Name":"Jill"
},{
"Id": 34,
"Name":"Jerena"
}]]

Output:

[30,33,34]

I’m stuck with this from sometime. Using maps
let Ids = [data[0][1]].map(a => a.Id);

>Solution :

Try this

let data = [3,[{
"Id": 30,
"Name":"John"
},{
"Id": 33,
"Name":"Jill"
},{
"Id": 34,
"Name":"Jerena"
}]]

console.log(data[1].map(r => r.Id))
