[b]Note:[/b] JSON objects do not preserve key order like Godot dictionaries, thus, you should not rely on keys being in a certain order if a dictionary is constructed from JSON. In contrast, JSON arrays retain the order of their elements: [codeblock] var p = JSON.parse('["hello", "world", "!"]') if typeof(p.result) == TYPE_ARRAY: print(p.result[0]) # Prints "hello" else: - print("unexpected results") + push_error("Unexpected results.")
