The `json.encode()` function converts a value into JSON bytes.

```js
import "json"

json.encode(v: "some value")
// Returns [34 115 111 109 101 32 118 97 108 117 101 34]
```

This function encodes [Flux types](/flux/v0.x/spec/types/) as follows:

- `time` values in [RFC3339](/influxdb/cloud/reference/glossary/#rfc3339-timestamp) format
- `duration` values in number of milliseconds since the epoch
- `regexp` values as their string representation
- `bytes` values as base64-encoded strings
- `function` values are not encoded and produce an error

## Parameters

### v {data-type="record, array, dict, string, bool, duration, int, uint, float, time"}
The value to convert.
