How does mobx.observable work?

mobx.observable is a function that creates a new observable object. An observable object is an object that can be tracked for changes, and any changes to its properties can automatically trigger updates in any computed values or reactions that depend on it. When a property is accessed, MobX automatically sets up a subscription that tracks any changes to that property and re-renders the UI when necessary.

 It wraps getting and setting object properties by setting path expression (dotted path - e.g. "Data.Person.FirstName", "Data.Person.LastName")

    function MobxPathObjectBinder(root, source) {
        this.root = mobx_1.observable(root);
        this.source = source === undefined ? this.root : source;
    }
    MobxPathObjectBinder.prototype.createNew = function (path, newItem) {
        //var item = followRef(this.root,newItem || this.getValue(path))

import { observable } from "mobx";

const person = observable({
  firstName: "John",
  lastName: "Doe",
  age: 30,
  get fullName() {
    return this.firstName + " " + this.lastName;
  },
  setAge(age) {
    this.age = age;
  },
});

person.setAge(35);

console.log(person.age); // Output: 35

In the above example, mobx.observable is used to create an observable object named person with properties such as firstName, lastName, age, and a computed property fullName. The setAge method of the person object is used to update the age property.
