Hi @TildaDares @jywarren, earlier I inadvertently left out the code L.Control.geocoder().addTo(map); in the file /examples/js/index.js when transferring js codes from /examples/index.html into /examples/js/index.js. Correction has now been made hence the need for this PR. Kindly review, many thanks.
