✅

Since you dont specify any options to draw it on the chart in your options and its not default chart.js behaviour I expect you defined it as defaults somewhere, in which case you can in your options object in the plugins section specify datalabels: false to stop it from rendering:

Chart.register(ChartDataLabels);
Chart.defaults.plugins.datalabels.color = '#fff';
Chart.defaults.plugins.datalabels.formatter = (value, ctx) => {
  let sum = 0;
  let dataArr = ctx.chart.data.datasets[0].data;
  dataArr.map(data => {
    sum += data;
  });
  let percentage = (value * 100 / sum).toFixed(2) + "%";
  return percentage;
};

const options = {
  type: 'doughnut',
  data: {
    labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
    datasets: [{
      label: '# of Votes',
      data: [12, 19, 3, 5, 2, 3],
      backgroundColor: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"]
    }]
  },
  options: {
    plugins: {
      datalabels: false // Removing this line shows the datalabels again
    }
  }
}

const ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);

options.plugins.datalabels: false should be mentioned.

Without it, the value is set to be true by default.
