About:
Tengo is a small, dynamically typed script language for Go with an emphasis on performance and safety. It compiles to bytecode, allowing it to run in embedded environments and within Go applications. Its primary value is enabling safe, fast user-defined configuration and logic without the overhead of a full interpreter.

Key Features:

Compiles to bytecode for fast execution
Sandboxed and secure for user-defined scripts
Statically typed with type inference
Seamless interoperability with Go
Small, embeddable runtime

Use Cases:

Embedding user-customizable rules and logic into Go applications
Safe execution of untrusted code for configuration
High-performance alternative to JSON or YAML for complex configs
Scripting automation tasks within Go programs

Alternatives:

Go-Lang – Go is a compiled systems language; Tengo is an embeddable scripting language for logic/configuration.
Lua – Lua is a widely used embeddable language; Tengo offers Go-native syntax and static typing.
Starlark – Starlark is used for build configurations; Tengo is optimized for general-purpose scripting in Go apps.
