Hi,
I have a long term experience with javascript and JSON object coding. In fact, I use JSON a lot when I provide Structured Data solutions to my SEO clients, according to the schema dot org syntax, and for inyect dynamic data into sites too.
Also, I'm very curiose about to know what is NGVD (National Geodetic Vertical Datum? I google it but I coudn't find anything beginer friendly)
Good bye proposal JSON tiny example:
{
'hope': "Hope you're interested in my service",
'wish': {
'pickone':true,
'niceday':'have a nice day',
'niceweek': 'have a nice week'
},
'accepted': 'I hope, again'
}
