-React uses trees to model the relationships between components and modules. 
+O React utiliza árvores para modelar as relações entre componentes e módulos.
 
-A React render tree is a representation of the parent and child relationship between components. 
+Uma árvore de renderização React é uma representação da relação pai-filho entre componentes.

-Components near the top of the tree, near the root component, are considered top-level components. Components with no child components are leaf components. This categorization of components is useful for understanding data flow and rendering performance.
+Os componentes próximos ao topo da árvore, perto do componente raiz, são considerados componentes de nível superior. Componentes sem componentes filhos são componentes folha. Essa categorização de componentes é útil para entender o fluxo de dados e o desempenho de renderização.
 
-Modelling the relationship between JavaScript modules is another useful way to understand your app. We refer to it as a module dependency tree. 
+Modelar o relacionamento entre módulos JavaScript é outra maneira útil de entender seu aplicativo. Chamamos isso de árvore de dependências de módulos.
 
 <Diagram name="generic_dependency_tree" height={250} width={500} alt="A tree graph with five nodes. Each node represents a JavaScript module. The top-most node is labelled 'RootModule.js'. It has three arrows extending to the nodes: 'ModuleA.js', 'ModuleB.js', and 'ModuleC.js'. Each arrow is labelled as 'imports'. 'ModuleC.js' node has a single 'imports' arrow that points to a node labelled 'ModuleD.js'.">

-A dependency tree is often used by build tools to bundle all the relevant JavaScript code for the client to download and render. A large bundle size regresses user experience for React apps. Understanding the module dependency tree is helpful to debug such issues. 
+Uma árvore de dependências é frequentemente usada por ferramentas de compilação para agrupar todo o código JavaScript relevante para o cliente baixar e renderizar. Um pacote muito grande prejudica a experiência do usuário em aplicativos React. Compreender a árvore de dependências do módulo é útil para depurar esses problemas.
