I'm looking for a way to copy wrapper list of content values to a single list

Example:

LIST<wrapper> dataAandB= [LIST A,LIST B] => List A =[Object X :{Id,Name ... }] and List B =[Object Y :{Id,Name, ...}]

let xObjlist = [];

xObjlist=List A;

Is it possible to copy without using data.forEach() ?

Yes. You can use concat:

var output = listA.concat(listB);

Or you can flatten it:

var output = [listA,listB].flat();

Arrays in JS are very robust. You should take time to study their many features on MDN.
