Flux is a functional data scripting language designed for querying, analyzing, and acting on time series data.

Its takes the power of [InfluxQL ](/influxdb/v1.8/query_language/spec/ ) and the functionality of [TICKscript ](/{{< latest "kapacitor" >}}/tick/introduction/ ) and combines them into a single, unified syntax.

> Flux v0.65 is production-ready and included with [InfluxDB v1.8](/influxdb/v1.8).
> The InfluxDB v1.8 implementation of Flux is read-only and does not support
> writing data back to InfluxDB.

## Flux design principles
Flux is designed to be usable, readable, flexible, composable, testable, contributable, and shareable.
Its syntax is largely inspired by [2018's most popular scripting language ](https://insights.stackoverflow.com/survey/2018#technology ),

JavaScript, and takes a functional approach to data exploration and processing.

The following example illustrates pulling data from a bucket (similar to an InfluxQL database) for the last five minutes,
filtering that data by the `cpu` measurement and the `cpu=cpu-total` tag, windowing the data in 1 minute intervals,
and calculating the average of each window:
```js
from(bucket:"telegraf/autogen")
|> range(start:-1h)
|> filter(fn:(r) =>
r._measurement == "cpu" and
r.cpu == "cpu-total"
)
|> aggregateWindow(every: 1m, fn: mean)
```
