Signal technology dates from the 1970s and revolutionized the way we think about reactivity in the user interfaces. The signals were the first to use the Knockoutjs library, and then they found their place in most modern libraries, such as Solidjs, Vue.js, Svelte.

🚀 The signal consists of the accessor (Getter) and Setter. The Setter sets the update of the value stored by the signal and activates all dependent effects. The accessory removes the value from the source and starts the effects every time the change occurs.

💡 There are two main ways to identify systems based on how they process their data: Pull (consumer asks updates from the source) and "Push" (the source sends updates as soon as they become available).

  • 📌 Signals help to create jet systems where data can notify the consumer about changes, and the consumer can apply these changes.
  • 📌 Push-Pull systems allow you to have a list of subscribers that can be activated to re-obtain data when updating occurs.
  • 📌 To create a jet system with "fine -grained" reactivity it is necessary to ensure efficiency (the system performs only a minimum of required calculations) and lack of errors (no intermediate states are shown during the updating).
🧩 Summary: Signals revolutionized the way we think about reactivity in the user interfaces, and continue to influence the development of UI. They help create effective and unmistakable systems that facilitate the work of developers.
🧠 Own considerations: although signals are not new technology, their impact on modern UI libraries continues to grow. Their ability to ensure efficiency and lack of errors makes them an important tool for user interfaces.
