![Advent of Svelte 2025 - Day 21: createContext #javascript #sveltejs #webdevelopment
Previously, sharing values through component trees required importing getContext and setContext, creating a Symbol to avoid string collisions, and exporting typed wrapper functions. With createContext, you simply call it with your type and get back a typed [get, set] tuple — no symbols, no strings, no boilerplate.
In this example, Santas naughty-and-nice list app uses createContext to share a notification function across deeply nested components.
