Is it possible to add an array to another array in one go?

Question

Is it possible to add an array to another array in one go?

Can anyone help me with using Google's geochart to draw a map with stats? I'm struggling to figure out how to combine my 2 arrays.

Here is the data I receive from the server:

[["DZ", 0], ["EG", 0], ["EH", 0], ...

and I need to put it into this array:

geoArray = [["Country", "Clicks"]];

Here is my current code:

async function drawRegionsMap() {
  geoArray = [["Country", "Clicks"]];

  await fetch(`http://127.0.0.1:80/grab`, {
    method: "post",
    headers: {
      Accept: "application/json",
      "Content-Type": "application/json",
    },

    body: JSON.stringify({
      token: token,
      key: "grab_geo_stats",
    }),
  })
    .then((response) => {
      return response.json();
    })
    .then((data) => {
      for (var i = 0; i < data.message.length; i++) {
        geoArray.push(data.message[i]);
      }

      var data = google.visualization.arrayToDataTable(geoArray);

      var options = {
        legend: "none",
        backgroundColor: "transparent",
        datalessRegionColor: "#62bcfc",
        colors: "#527aff",
        width: "695",
        height: "390",
        interactive: true,
        tooltip: {
          isHtml: true,
        },
      };

      chart = new google.visualization.GeoChart(
        document.getElementById("regions_div")
      );
      chart.draw(data, options);
    });
}

I want the final result to look like this:

[
    ['Country', 'Popularity'],
    ['Germany', 200],
    ['United States', 300],
    ['Brazil', 400],
    ['Canada', 500],
    ['France', 600],
    ['RU', 700]
]

To easily add data to the geoArray, you can utilize the spread operator:

geoArray.push(...someData);

In this scenario, someData represents the information you wish to insert into the geoArray array.

If we consider someData as

[["X", 0], ["Y", 0]]

, using push with the spread operator will effectively unpack the contents of someData and only include the individual items in the array.

This operation is equivalent to the following code snippet:

geoArray.push(["X", 0], ["Y", 0]);

To combine multiple arrays into a single array, you can use the following method ->

const combinedArray = [...array1, ...array2, ...arrayN];

If the data returned as a response is an Array, you can merge them like this,

const mergedData = [...firstArray, ...responseArray];

This approach will consolidate both arrays into one single array!

If you want to append the response data at the end of the geoData array instead of using a for loop like this:

for (var i = 0; i < data.message.length; i++) {
        geoArray.push(data.message[i]);

You have the option to simplify it by using spread syntax:

geoArray.push(...data)
