# The Tengo Language
[![GoDoc](https://godoc.org/github.com/d5/tengo?status.svg)](https://godoc.org/github.com/d5/tengo/script)
[![Go Report Card](https://goreportcard.com/badge/github.com/d5/tengo)](https://goreportcard.com/report/github.com/d5/tengo)
[![Build Status](https://travis-ci.org/d5/tengo.svg?branch=master)](https://travis-ci.org/d5/tengo)
[![](https://img.shields.io/badge/Support%20Tengo-%241-brightgreen.svg)](https://www.patreon.com/tengolang)
**Tengo is a small, dynamic, fast, secure script language for Go.**
Tengo is **[fast](#benchmark)** and secure because it's compiled/executed as bytecode on stack-based VM that's written in native Go.
```golang
/* The Tengo Language */
each := func(seq, fn) {
for x in seq { fn(x) }
}
sum := func(init, seq) {
each(seq, func(x) { init += x })
return init
}
n := sum(0, [1, 2, 3]) // == 6
s := sum("", [1, 2, 3]) // == "123"
```
> Run this code in the [Playground](https://tengolang.com/?s=d01cf9ed81daba939e26618530eb171f7397d9c9)
## Features
- Simple and highly readable [Syntax](https://github.com/d5/tengo/blob/master/docs/tutorial.md)
- Dynamic typing with type coercion
- Higher-order functions and closures
- Immutable values
- Garbage collection
- [Securely Embeddable](https://github.com/d5/tengo/blob/master/docs/interoperability.md) and [Extensible](https://github.com/d5/tengo/blob/master/docs/objects.md)
- Compiler/runtime written in native Go _(no external deps or cgo)_
- Executable as a [standalone](https://github.com/d5/tengo/blob/master/docs/tengo-cli.md) language / REPL
