Currently, this module only provides a means of parsing JSONC. JSONC serialization is not yet supported.

i'd like to be able to serialize object into JSONC with comments such as

const foo = { a: 1, b: 2 }

JSONC.stringify(foo)
//=> `{ 
//     "a":1,
//     "b":2,
//    }`

Describe the solution you'd like

add stringify to @std/jsonc
