Colon in javascript callback -


i'm using data layer on google maps point geometries use same coordinates. access of features @ given coordinate i'm trying use port of overlappingmarkerspiderfier data layer instead of markers called overlappingfeaturespiderfier.

i'm have problems adding click handler data layer. in documentation calls for:

ofs.addlistener("click", function(event: google.maps.data.mouseevent) {   var thefeaturethatwasclicked = event.feature; }

besides missing parenthesis, can't figure out what's going on colon in callback. ideas?

the colon syntax there typescript type annotation.

to use vanilla js, put function(event).
