Web developers are always at crossroads where they have to decide among a range of development frameworks and choose one for their project. It is a common topic of debate among developers on how to pick a framework for their next big project. Some frameworks which have become the most popular among developers and causing the dilemma are ReactJS, VueJS, and Angular. 

A simple difference between these three is that React is a UI library, and Vue is a progressive framework. However, Angular is a full-fledged front-end framework. As per StackOverflow Survey 2022, React is the favourite framework of 40.14% of developers, Angular with 22.96%, and Vue with 18.97% of developers. This guide focuses on helping you decide which framework to pick before starting your next project. 

In summary, the choice between Angular, Vue.js, and React.js often depends on factors such as project requirements, team expertise, scalability needs, and personal preferences. Each framework/library has its own strengths and weaknesses, so it's essential to evaluate them based on the specific needs of your project.
