Answer 1

This solution should work with Internet Explorer 10+, Edge, old and new versions of Chrome, FireFox, Safari, ++

The accepted answer won't work with IE and Safari.

// Example data given in question text
var data = [
  ['name1', 'city1', 'some other info'],
  ['name2', 'city2', 'more info']
];

// Building the CSV from the Data two-dimensional array
// Each column is separated by ";" and new line "\n" for next row
var csvContent = '';
data.forEach(function(infoArray, index) {
  dataString = infoArray.join(';');
  csvContent += index < data.length ? dataString + '\n' : dataString;
});

// The download function takes a CSV string, the filename and mimeType as parameters
// Scroll/look down at the bottom of this snippet to see how download is called
var download = function(content, fileName, mimeType) {
  var a = document.createElement('a');
  mimeType = mimeType || 'application/octet-stream';

  if (navigator.msSaveBlob) { // IE10
    navigator.msSaveBlob(new Blob([content], {
      type: mimeType
    }), fileName);
  } else if (URL && 'download' in a) { //html5 A[download]
    a.href = URL.createObjectURL(new Blob([content], {
      type: mimeType
    }));
    a.setAttribute('download', fileName);
    document.body.appendChild(a);
    a.click();
    document.body.removeChild(a);
  } else {
    location.href = 'data:application/octet-stream,' + encodeURIComponent(content); // only this mime type is supported
  }
}

download(csvContent, 'dowload.csv', 'text/csv;encoding:utf-8');

Running the code snippet will download the mock data as csv
