            Go REST is a GraphQL and RESTful API platform for testing and prototyping that delivers fake data with real responses, available 24/7 via public endpoints for users, posts, comments, and todos. It supports multiple API versions with full search on all fields, pagination (page and per_page), rate-limiting headers, and response format negotiation. Standard HTTP verbs are supported, and mutating requests require an access token via HTTP Bearer or query parameter. Nested resources let you retrieve related data, user posts, post comments, and user todos, while request and response logging, customizable rate limit,s and daily data resets ensure a clean testing environment. A GraphQL endpoint at /public/v2/graphql offers schema-driven queries and mutations.

            Simple, fast, safe, and compiled. For developing maintainable software. Simple language for building maintainable programs. You can learn the entire language by going through the documentation over a weekend, and in most cases, there's only one way to do something. This results in simple, readable, and maintainable code. This results in simple, readable, and maintainable code. Despite being simple, V gives a lot of power to the developer and can be used in pretty much every field, including systems programming, webdev, gamedev, GUI, mobile, science, embedded, tooling, etc. V is very similar to Go. If you know Go, you already know 80% of V. Bounds checking, No undefined values, no variable shadowing, immutable variables by default, immutable structs by default, option/result and mandatory error checks, sum types, generics, and immutable function args by default, mutable args have to be marked on call.
