-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)
-```
