Inserting data from arrays into a pie chart (chart.js)

Question

I have 2 arrays of data that I want to insert into a pie chart.

so I have this code:

new Chart(document.getElementById("pie-chart"), {
    type: 'pie',
    data: {
      labels: ["Africa", "Asia", "Europe", "Latin America", "North America"],
      datasets: [{
        label: "Population (millions)",
        backgroundColor: ["#3e95cd", "#8e5ea2","#3cba9f","#e8c3b9","#c45850"],
        data: [2478,5267,734,784,433]
      }]
    },
    options: {
      title: {
        display: true,
        text: 'Predicted world population (millions) in 2050'
      }
    }
});

Instead of writing the label and data, I want to get this information from 2 arrays (one for labels and one for data). How can I do it?
