Signals from Outer Space
summary
Examines signals as a minimal reactive primitive for JavaScript that aims to update only what’s necessary without proxies, memoization, or extra boilerplate. Covers how signals work, which frameworks have adopted them, the current TC39 proposal, and whether signals truly solve long-standing frontend reactivity problems or merely introduce new complexity with different syntax.
