It looks like you want to assign two values to your variable

jsonAr = {...},{...}

Maby you want to try somethig like this:

jsonAr = [{...},{...}]
jsonAr[0].coordinates[0][0] //25.9980559326738

Or

jsonAr = [{...},{...}]
draw_function(jsonAr[0].coordinates[0][0],jsonAr[1].coordinates[0][0]) //25.9980559326738,26.0486275566016

jsonAr.coordinates[0] will give you the first coordinate. jsonAr.coordinates[0][0] only gives you the first number of the first coordinate.
