React Version Compatibility

Node.js Version	LTS Status	React Version Compatibility	Notes
20.13.1	Active LTS	18.x, 19.x	Current active LTS; supports React 19.1.1 (latest as of July 2025) and 18.x; ideal for new projects.

Key Points:

• Node.js 20.13.1 (Active LTS since April 2024, supported until April 2026) is the only active LTS version as of August 2025. Node.js 18.x (Maintenance LTS) ended active support in April 2025 and is now in maintenance mode until April 2026, but it's less relevant for new React projects.
• React 19.x (released July 2025) and 18.x are compatible with Node.js 20.x, offering modern features like Server Components and improved performance.

powerful JavaScript frameworks/libraries for building user interfaces, have distinct approaches and syntaxes. Here's a breakdown of the basic syntax differences you'd encounter:

Fundamental Differences

• Angular (Framework): A full-fledged, opinionated framework that provides a structured way to build applications. It enforces a specific architecture (modules, components, services) and uses TypeScript as its primary language. Angular handles many aspects of development out of the box, offering a consistent and standardized approach.
• React (Library): Primarily a UI library, offering more flexibility. It focuses on building reusable UI components and lets developers choose other libraries for routing, state management, etc. React uses JavaScript (with JSX) and optionally TypeScript.

Summary of Key Differences

Feature	Angular 20 (TypeScript)	React 19 (JavaScript/JSX)
Philosophy	Opinionated framework, structured, "batteries-included"	Flexible UI library, "do-it-yourself" approach.
Language	Primarily TypeScript (mandatory).	JavaScript (ES6+ with JSX), optional TypeScript.
Components	Defined with @Component decorator on a TypeScript class. Uses separate HTML templates and CSS files. Supports standalone components.	Defined as JavaScript functions (or classes, though less common now) that return JSX. Logic and UI often co-located. React 19 introduces new conceptual component syntax for compiler optimizations.
Data Binding	Multiple explicit syntaxes: {{ }} (interpolation), [ ] (property binding), ( ) (event binding), [( )] (two-way binding via ngModel). New @if, @for for control flow.	Unified { } for embedding JavaScript expressions for both display and attribute/prop setting. onClick for events. Two-way binding via controlled components (value + onChange). Conditional and list rendering use standard JS methods (&&, map).
State Mgmt.	Component properties for local state. Services for shared state. NgRx for complex global state. Introduction of Signals for reactive state.	useState and useReducer hooks for local component state. Context API for global state. External libraries like Redux, Zustand, Jotai for more complex global state. React 19 adds new hooks for async operations and forms (useOptimistic, useActionState, useFormStatus).
Routing	Built-in @angular/router module.	Typically uses React Router (third-party library).
DOM Updates	Real DOM, uses change detection (Zone.js traditionally, now moving towards zoneless with Signals for performance).	Virtual DOM, leading to efficient updates.
Dependency Mgmt.	Strong built-in Dependency Injection system.	Achieved through prop drilling or Context API, or external state management libraries.

Choosing between Angular and React often comes down to project requirements, team familiarity, and preference for a structured framework versus a flexible library. Both are continually evolving, with Angular 20 focusing on performance improvements with Signals and better control flow, and React 19 streamlining async operations and enhancing compiler capabilities.
