is jquery replace javascript?

jQuery is indeed built on top of JavaScript and is not a standalone scripting language. It serves as a framework that simplifies the process of writing JavaScript code for web development. Browsers understand and process HTML, CSS, and JavaScript, and JavaScript libraries and frameworks like jQuery, Knockout, and Angular are written in JavaScript or languages that can be transcompiled to JavaScript (e.g., TypeScript for Angular).

These libraries enhance development by enabling the use of design patterns like MVC (Model-View-Controller), MVVM (Model-View-ViewModel), and others while ultimately generating JavaScript code to execute in the browser. This abstraction allows developers to work more efficiently and effectively while still using the power of JavaScript for web application development.

JavaScript libraries and frameworks

JavaScript libraries and frameworks like jQuery, Angular, and others are built on top of JavaScript and provide abstractions and tools to simplify web development. They don't replace JavaScript but enhance its capabilities and make it easier to work with.

However, the increasing popularity of such libraries and frameworks has led to a situation where many developers primarily work with these tools and may not explore deeply into the underlying JavaScript language. While this is a practical approach for many tasks, having a solid understanding of core JavaScript is still valuable, especially for tackling complex or unique programming challenges and for staying adaptable as technologies evolve.

ECMAScript 6 (ES6)

JavaScript itself has been continuously evolving, and you mentioned ECMAScript 6 (ES6) – this is one of the major updates that brought many new features and improvements to the language. JavaScript's ongoing development is essential for keeping up with the demands of modern web development.

Conclusion

While JavaScript libraries and frameworks can streamline development, they don't replace the need for understanding JavaScript itself. JavaScript continues to evolve and improve, ensuring its relevance in web development. Developers should ideally strike a balance between using libraries and frameworks and maintaining proficiency in core JavaScript.
