What is Time?

 What is Time?


What is time, exactly? Physicists define time as the progression of events from the past to the present into the future. Basically, if a system is unchanging, it is timeless. Time can be considered to be the fourth dimension of reality, used to describe events in three-dimensional space. It is not something we can see, touch, or taste, but we can measure its passage.

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?

 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.
