  1. What is jQuery?
    A JavaScript library.

  2. How does it help us as developers?
    It help us to do more by writing less. Making the process of building JavaScript webpages and applications easier and quicker.

  3. Why do we have 2 version of jQuery - minified and uncompressed?
    The minified version is lighter, and the recommended one for production sites. The uncompressed one has comments and it’s easier to read and modify. It’s also very convenient for debugging purposes.

  1. 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 regular JavaScript code.

  1. How does it help us as developers?

Adding animated effects to elements.
Making XML (Ajax) requests
Manipulating the [DOM]
Creating image slideshows.
Making drop-down menus
Creating drag-and-drop interfaces.
Adding power to forms

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

You can modify the uncompressed version but you would proaobly want to use the minified for your websites because of less size

  1. jQuery is a website that contains a lot of programs that have been written by other people and can be used by anyone.
  2. it makes it faster to create web pages.
  3. minified version is smaller and is made to be used in the actual console
    uncompressed version has commentaries and written with spaces which makes it easier to read but as a result makes the size of the file bigger.

1. What is jQuery?

Quite close sir, but JQuery is not an exactly website, it does have his own website to explain in detail about it. It’s an open-source library for JavaScript used to simplify the way to build web pages and web apps.

2. How does it help us as developers?

Yes, it does, by saving us time, since you can access to many features on some few lines of codes, instead on build and modify a large amount of code to achieve the same goal that you can do by using jquery.

Hope this gives you a clear view of the subject, keep learning! :slight_smile:

If you have any doubt, please let us know so we can help you!

A: makes it easy to write powerful JavaScript apps and create eye-catching animated effects rivalling those of Flash movies it also makes it easy to write JavaScript that works on many different browsers.

A: uncompressed .js files is easy to read and modify and has more kb data160kb and minified is quicker for users to download on your broswer and harder to read the code since it has less kb data 23kb

1.JQuery is a library of different pieces of code that accomplish certain common tasks.

2… It allows you to reference this code within your own programming by simply writting a single line of code instead of writing out the whole thing. It saves the programmer a lot of time.
3. one version is bulkier but much easier to read. The other version is harder to read and easier to download for visitors on your page.

  1. jQuery is a free JavaScript library that is by far the most used today.
  2. It helps developers take pieces of existing code to incorporate into their program to cut down on unnecessary programming time.
  3. Uncompressed is larger but is easy to modify and ready. Minified is much more difficult to read/modify but is smaller for users to download much quicker.

  1. It is the most popular JavaScript library in use today.

  2. Lets us build webpages and webapps quicker and easier.

3.Uncompressed you can read all the details but takes longer to load. Minified is difficult to read because a lot of the detail is removed but makes it much quicker to load.

1. What is jQuery?

  • jQuery is a Javascript library that makes it easier for developers to develop webpages and Apps.

2. How does it help us as developers?

  • We can write much smaller pieces of code with jQuery with exactly the same fuctionality as larger pieces of code. In other words it will save us a lot of time and effort.

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

  • The first version is a much smaller file and it downloads much quicker to your site. This is the file you’ll want to use. The uncompressed version has much more information and is easier to read. If you find it difficult to understand a jQuery function you can always refer back to the uncompressed version for more info.

  1. jQuery is a javascript library containing many common features for webpages.
  2. It allows us to build webpages more easily, with less code.
  3. The minified version is meant to load fast if we want to use it unmodified. The compressed is for people who want to look at and perhaps edit the jQuery code.

  1. jQuery is a mainstreamed library of its own that has been used on many web pages. jQuery allows you to do all sorts of stuff like adding animated effects, creating image slideshows and making drop down menus etc. Without jQuery people would have made bundles of script that would have taken too long of a time but since we have this library, a lot of the code is much easier and simpler to write.

  2. Before jQuery, coding would have been taking a much longer time. Writing something like a photo slide would have taken more than 10 lines and programmers who might have been lost on a specific part of script and don’t know about libraries like jQuery could have been stuck for days. With this library however coding becomes not as hard and lets us work around corners when we get lost.

  3. Uncompressed is easy to read and modify. When it is posted on the server the code that was written doesn’t really change. It leaves everything as the creator intended. Minified however takes out things like comments and whitespaces(empty areas with no code) and makes it a smaller download size. This makes it faster to download websites and is recommended to be used instead of uncompressed.

  1. JQuery is a public software library where the developer can save a lot of time by implementing existing code into the app that is being built.
  2. So JQuery is a library that can inspire and help developers to be more efficient and creative. Also, me as a beginner of JavaScript programming, can benefit big time, by using experienced programmers codes and modules to implement into my projects.
  3. The uncompressed version of jQuery is consisting of codes, comments and some overflow of information. This is a good version to use to be able to interpret the code as well as help other developers in the project later on, when the code needs to be changed. The minimized version is consisting of the same code, but all the overflow of comments etc. is removed, makeing the .js file smaller and quicker for users to download.

  1. jQuery is a free JavaScript library.
  2. Basically, it saves developers time. It lets developer to build something new from existing jQuery blocks. Developer gets great functionality with less code, plus every browsers select and downloads appropriate jQuery, so a web pages looks nice on all browsers.
  3. My guess is that, developers uses uncompressed version, which just looks better to human eye, while during normal network operations minified version is used due to smaller bit size.

  • It helps us as developers to write easily complex codes, it gives us more for less effort.

  • Why do we have 2 version of jQuery - minified and uncompressed?
  • Because of the visitiors, the uncompressed is easy to read and modify but is larger in size, while the minified has all comments, whitespace, and other unnecessary characters removed from the file, squeezing the whole library into a mere 23kb. So it is way easier for visitors to download it :slight_smile:

  3. Why do we have 2 version of jQuery - minified and uncompressed?
    Minification isn’t compression in the classic sense. It refers to the removal of white space and other nonessential characters like comments so that the code is still valid but as compact as possible. It’s effectively a form of code obfuscation. As such, it is not recommended for development because it makes the code much less readable and much harder to edit.
    Compressed code would have to be “uncompressed” first before execution. Minified code is still valid code in all respects and can be run immediately.
    Minification happens anyway as part of the compilation process in most languages. By pre-minifying the files, you simply speed up the download and parsing process by a certain amount.

jquery.js = Pretty and easy to read :slight_smile: Read this one.
jquery.min.js = Looks like jibberish! But has a smaller file size. Put this one on your site.

Both are the same in functionality. The difference is only in whether it’s formatted nicely for readability or compactly for smaller file size.
