Locutus is a collection of ~800 TypeScript implementations of standard library functions from 18 programming languages such as PHP, Go, Python, Ruby, and C. Each function is individually importable and tree-shakeable via npm, porting function semantics rather than foreign runtime data structures.

Use cases

• use php sprintf in javascript
• port a go strings.Contains call to typescript
• match behavior of another language's stdlib function in js
• learn how different languages implement the same functions
• import a single stdlib function with minimal bundle size
• migrate code from php or python to javascript

When to choose

• you need parity with a specific function from PHP, Go, Python, Ruby, or another ported language
• you want a single tree-shakeable function rather than a full utility framework
• you are studying or teaching how other languages' standard libraries work

When to avoid

• you need a general-purpose utility toolkit for TypeScript (use lodash instead)
• your target JavaScript environments already provide the functionality natively
• you need foreign language data structures or runtime objects, not just function behavior
