Hi - I have a below code. I am trying to add a map marker using OpenStreetMap with leaflet. I am not sure if I can write the below marker code without google.maps and use openStreetmap for the below code. I want to avoid using google maps because I am not going to buy Google API key and wanted to use something free to create a map with a marker as I am just learning to create a map project. `f
unction createMarker(latlng, name, address, index) {`
` var html = "<b>" + name + "</b> <br/>" + address;`
` var marker = new google.maps.Marker({`
` map: map,`
` position: latlng`
` });`
the above code gave error, Uncaught ReferenceError: google is not defined
. then I defined to rectify that error. right now, the error is gone, but in the output, i dont see any marker in map and I get warning message asGoogle Maps JavaScript API warning: NoApiKeys. please suggest and direct me to go right to solve this one.
