Working with Injectors and Hierarchies</h2> <p>In the previous chapter, we learned about services, providers, and how to create a basic injector. Now, let&rsquo;s dive deeper into how <code>ReflectiveInjector</code> resolves dependencies and, more importantly, how to build sophisticated <strong>injector hierarchies</strong> to manage dependencies in large, modular applications.</p> <h3 id="the-role-of-reflectiveinjector">The Role of <code>ReflectiveInjector</code></h3> <p>The <code>ReflectiveInjector</code> is the central component that <code>injection-js</code> uses to resolve dependencies. When you call <code>injector.get(SomeToken)</code>, it performs the following steps:</p>
