What is jQuery?
What is jQuery?
jQuery is a classic JavaScript library that’s fast, light-weight, and feature-rich. It was built in 2006 by John Resig at BarCamp NYC. jQuery is free and open-source software with a license from MIT.
It makes things simpler for HTML document manipulation and traversal, animation, event handling, and Ajax.
According to W3Techs, 77.6% of all sites use jQuery (as of 23rd February 2021).
Features/Benefits:
It has an easy-to-use, minimalistic API.
It uses CSS3 selectors in manipulating style properties and finding elements.
jQuery is lightweight, taking just 30 kb to gzip and minify, and supports an AMD module.
As its syntax is quite similar to that of CSS, it is easy for beginners to learn.
Extendable with plugins.
Versatility with an API that supports multiple browsers, including Chrome and Firefox.
Use cases:
DOM manipulation with CSS selectors that use certain criteria to select a node in the
DOM. These criteria include element names and their attributes (like class and id).
Element selection in DOM using Sizzle (an open-source, multi-browser selector engine).
Creating effects, events, and animations.
JSON parsing.
Ajax application development.
Feature detection.
Control of asynchronous processing with Promise and Deferred objects.
What Are JavaScript Libraries?
What Are JavaScript Libraries?
JavaScript libraries contain various functions, methods, or objects to perform practical tasks on a webpage or JS-based application. You can even build a WordPress site with them.
Think of them as a book library where you revisit to read your favorite books. You may be an author and enjoy other authors’ books, get a new perspective or idea, and utilize the same in your life.
Similarly, a JavaScript library has codes or functions that developers can reuse and repurpose. A developer writes these codes, and other developers reuse the same code to perform a certain task, like preparing a slideshow, instead of writing it from scratch. It saves them significant time and effort.
They are precisely the motive behind creating JavaScript libraries, which is why you can find dozens of them for multiple use cases. They not only save you time but also bring simplicity to the entire development process.

Importance of CSS
Importance of CSS
CSS (Cascading Style Sheets) is crucial for web development and design for several reasons:
1. **Separation of Content and Presentation**:
- CSS allows developers to separate the content of a website (HTML) from its visual presentation. This separation makes it easier to manage and maintain the website. Changes in the design can be made in the CSS file without altering the HTML structure.
2. **Improved Accessibility**:
- By separating style from content, CSS enhances accessibility. Screen readers and other assistive technologies can more easily interpret and navigate content that is structured with HTML and styled with CSS.
3. **Consistency Across Pages**:
- CSS enables the application of a consistent style across multiple web pages. This uniformity ensures that all pages of a website look cohesive, which improves user experience and brand identity.
4. **Enhanced Design and Layout**:
- CSS provides powerful tools for creating visually appealing and responsive designs. Features like Flexbox, Grid, and media queries allow developers to create complex layouts that adapt to different screen sizes and devices.
5. **Performance Optimization**:
- CSS can help improve website performance. External CSS files are cached by browsers, which reduces the need to reload the same styles with every page request. This caching speeds up page load times.
6. **Reduced HTML Complexity**:
- By moving style rules to a separate CSS file, HTML documents become cleaner and more readable. This simplification makes it easier to spot and fix errors in the HTML code.
7. **Reusability**:
- CSS classes and IDs can be reused across different elements and pages, which reduces redundancy and makes the codebase more efficient. Reusability also speeds up development time and reduces the likelihood of errors.
8. **Maintainability**:
- CSS makes it easier to maintain and update a website. A single change in a CSS file can update the style of multiple pages at once, simplifying the process of making site-wide changes.
9. **Animation and Interactivity**:
- CSS provides capabilities for adding animations and transitions to web elements, enhancing the user experience without the need for JavaScript or other more complex technologies.
10. **Industry Standards and Best Practices**:
- CSS is a standard defined by the World Wide Web Consortium (W3C). Following these standards ensures compatibility across different browsers and devices, making websites more reliable and accessible.
In summary, CSS is fundamental to web development because it enhances design capabilities, improves user experience, ensures consistency, and makes the code more maintainable and efficient.
