Tengo is **[fast](#benchmark)** and secure because it's compiled/executed as bytecode on stack-based VM that's written in native Go.
|
||||
|
||||
> Try Tengo in the [Playground](https://tengolang.com/).
|
||||
```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"
|
||||
```

## Features
|
||||
|
||||
- Similar [syntax](https://github.com/d5/tengo/blob/master/docs/tutorial.md) to Go but much simpler
|
||||
- Dynamically-typed with type coercions
|
||||
- First-class functions and closures
|
||||
- Garbage-collected
|
||||
- [Embeddable](https://github.com/d5/tengo/blob/master/docs/interoperability.md) and [Extensible](https://github.com/d5/tengo/blob/master/docs/objects.md)
|
||||
- Written in native Go _(no external deps or cgo)_
|
||||
- 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 _(v1)_
|
||||
- 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
