React and Angular are two leading JavaScript frameworks widely used in building web applications, with React claiming a larger market share. React, developed by Meta, is known for its component-based architecture, virtual DOM, and unidirectional data flow, making it efficient and flexible for developers who prefer an open-ended approach. Angular, created by Google, offers a more complete MVC solution with two-way data binding and dependency injection, appealing to those who favor a structured, opinionated framework. Both have their strengths and weaknesses: React is easier to learn and faster due to its virtual DOM, while Angular provides a comprehensive framework but has a steeper learning curve and can be slower due to its real DOM usage. React's community support and adaptability make it the preferred choice for many developers, though Angular remains significant, especially in large-scale projects needing rigorous code standards. While React is often favored for its flexibility and speed, Angular's structured approach is still valued in certain scenarios, particularly in legacy systems and by experienced developers.
