Vanilla JavaScript, also known as plain or pure JavaScript, is the term used to refer to JavaScript that is not extended or modified by any additional libraries or frameworks. In the world of web development, there are many popular libraries and frameworks that provide additional features and capabilities to JavaScript, such as jQuery, React, and Angular. However, despite the popularity of these libraries and frameworks, it is still important to understand and be proficient in vanilla JavaScript.
One of the main reasons why vanilla JavaScript is important is that it is the fundamental building block of the web. All web browsers include a JavaScript engine that can execute JavaScript code, and this is what allows web applications and websites to be interactive and dynamic. In order to create web applications and websites that work well and are efficient, it is essential to have a solid understanding of the core features and capabilities of JavaScript.
Another reason why vanilla JavaScript is important is that it is widely supported and compatible with all modern web browsers. Unlike many libraries and frameworks, which may have specific requirements or dependencies, vanilla JavaScript is guaranteed to work in any web browser that supports JavaScript. This means that you can use vanilla JavaScript to create web applications and websites that can be accessed by a wide range of users, regardless of the browsers and devices they are using.
In addition, vanilla JavaScript is often more lightweight and performant than many libraries and frameworks. Because it does not include any additional features or abstractions, vanilla JavaScript is typically smaller and faster than many libraries and frameworks. This can be especially important for applications that need to be fast and responsive, or that need to work on devices with limited resources.
Overall, while there are many powerful libraries and frameworks available for JavaScript, it is still important to have a strong foundation in vanilla JavaScript. Understanding the core features and capabilities of the language can help you create better web applications and websites, and it can also make it easier to learn and use other libraries and frameworks. By mastering vanilla JavaScript, you can become a more versatile and effective web developer.
