What is jQuery?
jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps.
With jQuery, you can write a single line of code to achieve what would have taken 10-20 lines of regular JavaScript code.
How does it help us as developers?
Its time saving and efficient
With jQuery, you can write powerful JavaScript apps using fewer lines of code.
Why do we have two versions of jQuery - minified and uncompressed?
Both give the same functionality, but minified.js has compressed all the data into one chunk of text and minimizing
the file size witch also makes the website load faster.
The uncompressed .js file is cleaner and easier to read and modify but is larger in size.
