A high-performance 100% compatible drop-in replacement of "encoding/json"

# Benchmark

![benchmark](http://jsoniter.com/benchmarks/go-benchmark.png)

Source code: https://github.com/json-iterator/go-benchmark/blob/master/src/github.com/json-iterator/go-benchmark/benchmark_medium_payload_test.go

Raw Result (easyjson requires static code generation)

|                 | ns/op       | allocation bytes | allocation times |
| --------------- | ----------- | ---------------- | ---------------- |
| std decode      | 35510 ns/op | 1960 B/op        | 99 allocs/op     |
| easyjson decode | 8499 ns/op  | 160 B/op         | 4 allocs/op      |
| jsoniter decode | 5623 ns/op  | 160 B/op         | 3 allocs/op      |
| std encode      | 2213 ns/op  | 712 B/op         | 5 allocs/op      |
| easyjson encode | 883 ns/op   | 576 B/op         | 3 allocs/op      |
| jsoniter encode | 837 ns/op   | 384 B/op         | 4 allocs/op      |

Always benchmark with your own workload.
The result depends heavily on the data input.

# Usage

100% compatibility with standard lib

Replace

```go
import "encoding/json"
json.Marshal(&data)
```

with

```go
import jsoniter "github.com/json-iterator/go"

var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Marshal(&data)
```

Replace

```go
import "encoding/json"
json.Unmarshal(input, &data)
```

with

```go
import jsoniter "github.com/json-iterator/go"

var json = jsoniter.ConfigCompatibleWithStandardLibrary
json.Unmarshal(input, &data)
```
