Standard Library Overview

FScript’s standard library is explicit by design. Helpers live in imported std: modules rather than on prototype chains or global namespaces.

Core principles

standard-library modules use the reserved std: scheme
default imports are the normal pattern for std: modules
functions are curried by default
transformation helpers are usually data-last
collection helpers never mutate caller-visible data

Example

import Array from 'std:array'

names = users
  |> Array.filter((user) => user.active)
  |> Array.map((user) => user.name)

That style works because Array.filter and Array.map are designed for pipes and partial application.

Core Draft 0.1 modules

std:array
std:object
std:string
std:number
std:result
std:json
std:logger
std:filesystem
std:task

Comparison to JavaScript

Instead of items.map(...) or text.trim(), FScript uses imported helpers such as Array.map(...) and String.trim(...). That keeps behavior explicit and avoids depending on prototype methods.

Current implementation note

The current runtime already ships substantial runtime-backed std: support, including filesystem, JSON, logging, and task helpers. As with the rest of Draft 0.1, the documented surface is intentionally small and focused.
