JSON

Quicktype is nice tool for building models from JSON. JSON Hero is nice JSON viewer.

Notes

• I wish JSON.parse had an option to allow comments and trailing commas. There's a whole world of config files in companies that the built in platform can't handle. Installing jsonc or json5 is one of the first things I do everywhere.
