JSON parser and object model

The Parser

The parser does not fully validate parsed values. The validation happens in "getter" methods: GetString(), GetInt(), etc.

This approach makes parsing 3 times faster than standard GO parser:

jo, err := ParseObjectString(`{ "name": "YM", "age": 27 }`)
ja, err := ParseArrayString(`[ "xyz", 123 ]`)

The Model

// create new object and add two properites
jo := New().Add("name", "YM").Add("age", 27)

// add more properties
jo.Add("pi", 3.14)
jo.Add("ok", true)

// remove properties
jo.Remove("pi")

// get value
s, ok := jo.GetString("name")
i, ok := jo.GetInt("age")

// create new array
ja := NewArray([]string{ "abc", "xyz" })

// add more values
ja.Add(3.14)
ja.Add(true)

// remove value
ja.Remove(3)

// get value
s, ok := ja.GetString(0)
i, ok := ja.GetFloat(2)
