Iterate JSON where Member Names are Data Values

Demonstrates how to parse JSON where member names are not keywords, but instead are data values.Chilkat Zig Downloads
const std = @import("std");
const chilkat = @import("chilkat");
pub fn main(init: std.process.Init) !void {

// Imagine we have JSON such as the following:
// {
// "1680": {
// "entity_id": "1680",
// "type_id": "simple",
// "sku": "123"
// },
// "1701": {
// "entity_id": "1701",
// "type_id": "simple",
// "sku": "456"
// }
// }
//
// This presents a parsing problem because the member names, such as "1680"
// are not keywords. Instead they are data values. We don't know what they
// may be in advance.
// To solve, we iterate over the members, get the name of each, ...
