  1. jQuery is the most commonly used library for building JavaScript websites and apps.
  2. jQuery comes in a single line of code, vs the same code that can take up to 20 lines.
  3. jQuery comes in two versions, there is the uncompressed file- which is larger in size, but its easy to read and understand the code. Then there is the minified version- that version is much smaller and is ideal for faster downloading, but its not easy to read code.

  1. jQuery is a library that makes it more time efficient and more convenient to build JavaScript webpages and web apps.

  2. It helps in many ways as developers for example things like animation, Ajax request, DOM manipulation, image effects. It also lets us write cross-browser JavaScript code.

  3. The uncompressed version lets us easily read but bigger in size, and modify version is smaller in size but its the best version to place on a site.

1. What is jQuery?

jQuery is the most popular free Javascript library.

2. How does it help us as developers?

jQuery is extremely helpful because it saves us a ton of time and helps us build better webpages and apps faster. It does this by preventing browser compatibility issues, and allows us to make better animated effects, create drag and drop interfaces, drop down menus and lots more.

3. Why do we have 2 version of jQuery - minified and uncompressed?

The minified version contains just the essentials, the actual code itself, and is therefore a much smaller file. The uncompressed version is much easier to read because it contains comments and other text.

The smaller file is faster to download, but the larger file is more detailed (and slower for users to load)

What is jQuery?

  • jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps. (Often with jQuery you can write a single line of code to achieve what would have taken 10-20 lines of vanilla JavaScript).

  • jQuery is itself written in JavaScript, and comes in the form of a single .js file that you link to from your webpage. (Your JavaScript code then accesses the library by calling various jQuery functions).

How does it help us as developers?

  • jQuery makes it easy to write powerful JavaScript apps and create eye-catching animated effects rivaling those of Flash movies.

-Adding animated effects to elements:

—>fading in/out

—>sliding in/out

—>expanding/contracting

-Making XML (Ajax) requests:

—>These use JavaScript to request additional data from the Web server without having to reload the page.

-Manipulating the DOM:

—>You can easily add, remove, and reorder content in the Web page using just a couple of lines of code.

-Creating image slideshows:

—>You can use jQuery effects to build nice animated slideshows and lightboxes.

-Making drop-down menus:

—>jQuery makes it easy to create multi-level dropdown with animations.

-Creating drag-and-drop interfaces:

—>Use jQuery to build a page with elements that can be repositioned or reordered simply by dragging and dropping.

-Adding power to forms:

—>With jQuery you can easily add complex client-side form validation, create auto-complete Ajax text fields that pull data from a server-side database, and so on.

Why do we have 2 versions of jQuery - minified and uncompressed?

  • The jQuery library actually comes in 2 forms:

-The uncompressed .js file is easy to read and modify, but it’s around 160kb in size (at the time of writing).

-The minified .js file has all comments, whitespace, and other unnecessary characters removed from the file, squeezing the whole library into a mere 23kb. Although you can’t easily read the code, this is the version you’ll want to place on your site, as it’s much quicker for visitors to download.

How does it help us as developers?

  • a lot of functionality is available with this library

Why do we have 2 version of jQuery - minified and uncompressed?

  • if implemented the smaller version minified, your site will be faster downloaded by visitors
  • the uncompressed version is easier to read for developers beacuse of the comments which are still in place

  1. JQuery is JavaScript code in the for of a file with the type being .js.

  2. A developer can reference the .js and instead of writing +20 lines of code can instead write just one.

  3. The uncompressed.js is easier for humans to read and use but is not fast. The minified.js is faster and should be used in production.

  • What is jQuery?

jQuery is a library which make it quicker, easier, and cleaner to build web pages and apps.

  • How does it help us as developers?

Up to twenty lines of regular JavaScript code can be written with a single line of code in jQuery.
Incompatibilities between popular browsers such as IE, Firefox and Safari is no longer problem, you just call the appropriate jQuery function and let it deal with it.

  • Why do we have 2 version of jQuery - minified and uncompressed?

Full version takes 160kb of space the minified only 23kb and this is the version you’ll want to place on your site, as it’s much quicker for visitors to download.

  3. Uncompressed jQuery version is used for modifications of the code and functionality and 267KB in size, easily readable for humans with lots of whitespace and comments to help in understanding the code.
    Minified version has all the unnecessary characters removed from the source code without changing its functionality and 32KB in size - faster file downloading for users.

  1. jQuery is a library that makes it quicker and easier to build Javascript webpages and web apps.
  2. Using jQuery, we can write powerful Javascript apps using fewer lines of code by re-using someone else’s made functionalities which available for public for free. So it saves time and allows developers to think improving more complex codes.
  3. The uncompressed version is easy to read and modify, whereas the minified version is shrinked so it is more difficult to read. However, a mean thing is that the first version is bigger in size and the second is a lot more smaller which makes it easier for the clients to download the webpage faster.

  1. JQuery is a very popular and widely used library.
  2. JQuery gives developers access to a wide range of functions that they can use in order to save the time and resources it would take to write this code on their own. It also allows for functionality across all browsers, which helps developers avoid writing different code for each browser.
  3. The uncompressed file is much easier to read, but very large. The minified version is much harder to read (as it takes out all of the whitespace and comments removed from the file, making it smaller and quicker to load.
