DataLayer - list of all skus purchased

Question

Hi please how would you set the variable to get the list of all skus purchased which are in an array in the data layer? For example:

transactionProducts:[

{sku: “1234”, name: “product 1”, price: “2.99”, quantity: “1”}
{sku: “5678”, name: “product 2”, price: “5.99”, quantity: “1”}
{sku: “9012”, name: “product 3”, price: “8.49”, quantity: “2”}

]

From the above array, I would want to get each sku value and have it return together as the value of the variable. So something like '1234', '5678', '9012'

Because now I make variable transactionProducts.0.sku but its only one.

Is there any way to do that? Thank you

If you want to use a custom JS in GTM:

function () {
sku = []
for (i=0; i< transactionProducts.length; i++) { 
    sku.push(transactionProducts.i.sku); 
   }
return sku;
}
