jQuery Reading Assignment

[Chocolate]

1. What is jQuery?
   jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps.

2. How does it help us as developers?
   It helps us write javascript apps fairly easily instead of writing everything from scratch.

3. Why do we have 2 version of jQuery - minified and uncompressed?
   The uncompressed one is well documented and presented in a way that is easy to read and understand.
   Minified contains only the bare minimum for the code to function as intended in order to save space, and as a result will not be as easy to read.

1. What is jQuery?
   j Query is a javascript library.
2. How does it help us as developers?
   It saves time on writing code.
3. Why do we have 2 version of jQuery - minified and uncompressed?
   The uncompressed javascript file is easy to read and modify, but it’s around 160kb in size.
   The minified .javascript file has all comments, whitespace, and other unnecessary characters removed from the file, squeezing the whole library into 23kb.

Hi @Chocolate,

Your answers show that you have the right idea. Here is some additional information to expand on them.

2. How does it help us as developers?
   It helps us write javascript apps fairly easily instead of writing everything from scratch.

Yes… and jQuery also helps developers build dynamic and interactive websites and web apps with powerful functionality. It also deals with browser incompatibility issues so that developers don’t have to concern themselves with this.

@jon_m

In terms of building a dynamic and interactive experience for the user, jQuery also helps developers to:

• manipulate the DOM;
• animate elements by fading or sliding them in/out, or by expanding/contracting them;
• implement drag-and-drop functionality for re-ordering and moving elements;
• implement client-side form validation;
• make Ajax requests for additional data from the server, without the web page having to be reloaded e.g. autocompletion of forms;
• create high-quality slideshows and dropdown menus.

Minified contains only the bare minimum for the code to function as intended in order to save space, and as a result will not be as easy to read.

Yes…the comments, whitespace and certain characters have been removed from the minified version. The completed product should link to this version because it can be downloaded much more quickly by the user.

Hi @Jason_Tibbetts,

Your answers show that you have the right idea. Take at look at this post for some more detail.

1. jQuery is a free, popular library that makes it quicker and easier to build JavaScript webpages and web apps.

2. We do not need to write code from scratch but use already written codes, such as animation and other useful stuff.

3. jQuery library has 2 forms:

• The uncompressed .js file is easy to read and modify, but it’s big…
• The minified .js file has all comments, whitespace, and other unnecessary characters removed from the file, squeezing the whole library into a smaller size.

[sherlock]

1. It’s a library in form of a file that you can link to your webpage. It contains functions which enables build webpages and web apps easier and quicker way.
2. Answered in 1.
3. The uncompressed file is easy to read and modify but it’s quite big. Whereas at the minified file all comments, whitespace, and other unnecessary characters have been removed. Thus it’s hardly readable but way smaller and is usually used by programmers

[Kingsman]

1. What is jQuery?
   jQuery is simply an open-source JavaScript Library designed to simplify the client-side scripting of HTML.
2. How does it help us as developers?
   It helps save time and avoids writing functions and code from scratch.
3. Why do we have 2 version of jQuery - minified and uncompressed?
   The uncompressed version is easy for developers to read and get a hang of using it because of the comments but the file size is large. The minified version is practical for actual use case within websites, it has no comments, punctuation’s, or spaces, so its easier and faster when the end user runs your website or program.

[jon_m]

Good answers, @Ball

@Ball

• The uncompressed .js file is easy to read and modify, but it’s big…

Yes … and I would just add that that’s why it’s used during development.

@Ball

• The minified .js file has all comments, whitespace, and other unnecessary characters removed from the file, squeezing the whole library into a smaller size.

Yes … and I would also add that that’s why the completed product should link to this version because it can be downloaded much more quickly by the user.

Hi @sherlock,

@sherlock

3. The uncompressed file is easy to read and modify but it’s quite big. Whereas at the minified file all comments, whitespace, and other unnecessary characters have been removed. Thus it’s hardly readable but way smaller…

That’s correct

@sherlock

… the minified file… is usually used by programmers

Just to clarify… the completed product should link to this version because it can be downloaded much more quickly by the user due to its much smaller size.

The uncompressed version is used by programmers during development, because, as you have said, it is easier to read and modify.

1. jQuery is a javascript library that makes it easier and faster to code websites.

2. It allows you to code once and have it automatically adapted to multiple browsers. Also allows for less script needed to create the same functionality.

3. The minified version of jQuery is a smaller sized file and allows for faster loading on the website. It has all the blank spaces taken out to create a smaller file, but is difficult to read as a human.

The uncompressed version is easier to read and is spaced out the way the code would have actually been written, but is a larger file size that would take longer to load the webpage.

[John_Okoye]

jQuery is JS code that performs a specific function. It’s like a paragraph in an article. It conveys an idea (jQuery) to the whole purpose or meaning of the article (the APP).

all stories (APPS) and books are made up from the same ideas (jQueries) really, they just are rearranged in a fashion that creates a unique overall. piece of work (APPs).

jQuery is how this almost illiterate man was able to get through undergraduate and professional school without reading much…it is the CLIFFS/COLES notes or the ABSTRACT in professional journals. Uncompressed is the War and Peace novel or that full published research paper that the fully literate people of this world use…but partially literate people actually do have a lot of value, lol

[sherlock]

Alright,…thank you for the clarification

What is jQuery?
-jQuery is a JS library that makes developinping quicker and easier.

How does it help us as developers?
-jQuery makes it easy to write powerful JavaScript apps, adding animated effects to elements, making XML (Ajax) requests, manipulating the DOM, creating image slideshows, making drop-down menus and more. It makes it easy to write JS that works on many different browsers and allows for less script needed to create the same functionality.

hy do we have 2 version of jQuery - minified and uncompressed?
-“Minified” are compressed versions of the original files. Most of the compression is achieved by eliminating whitespace and changing variable names to shorter character lengths.“uncompressed” is used for development when you need to read the code for debugging.

[AF90]

1. jQuery is a JavaScript library.
2. jQuery helps developers as it contains many commonly used functions written as consolidated code, so by using jQuery, you can achieve the same outcome with what could have taken 2-30 lines of JavaScript.
3. jQuery contains 2 versions. The uncompressed version is easier to read and good as a reference material, but larger in file size. The minified version is small in size, but difficult to read. It is best to link the minified version of jQuery from your website.

What is jQuery?

jQuery is a library that gives you as developer tons of functions to create a JavaScript website and web apps.

How does it help us as developers?

With jQuery can the developer write powerful JavaScript apps with few line of code.

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

Because one is for developing and debugging (uncompressed) and the minifed is for saves bandwidth and improves performance in production.

1. What is jQuery?
   jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps
2. How does it help us as developers?
   Can use a function tool from library instead of building yourself
3. Why do we have 2 version of jQuery - minified and uncompressed?
   One larger easier to read and modify for development/editing/design which is slightly larger is the uncompressed one. The minified one is for your actual webpage to use so visitors download it faster reducing amount to download by roughly 8x (160kb-23kb)

[Mario_M]

1. jQuery is a free JavaScript library that makes it quicker and easier to build JavaScript webpages and
   web apps.
2. You donnt have to rewrite code. So it saves a lot of time.
3. Uncompressed is readable code and is striped from not nesessary data. Minified uses less data
   because is stripped from unnesessary data. This is used used to make a website load faster.

[elez]

1. What is jQuery?
   A Query is JS codeing templets its a library that gives the developer acces to faster bild app and websites. It is also comes unconpressed (you can see all coding and modify but its bigger KB) or minified ( has all comments, whitespace, and other unnecessary characters removed from the file, squeezing the whole library into smaller space, which makes it faster to download).
2. How does it help us as developers?
   jQuery allows developers to invoke a lot of common tasks that require many lines of JavaScript code to accomplish, and wraps them into methods that you can call with a single line of code.
3. Why do we have 2 version of jQuery - minified and uncompressed? look at Q1 above.

[hoolie]

1. What is jQuery?
   A library of javascript that can be used in your own programs

2. How does it help us as developers?
   We can copy and paste other peoples code for a particular part of our program thus speeding up the entire process of writing code

3. Why do we have 2 version of jQuery - minified and uncompressed?
   Uncompressed is easy to read and modify but is 160k in size
   minified is compressed with all unnecessary spaces and characters removed making it hard to read , but is recomended for your program due to its faster load times

[ArvidK]

1. A type of library for web developers.
2. JQuery offers code that functions on all browsers, the codes can in theory just be copy-pasted to our website so that we don’t have to write ur own codes, and JQuery also offers single-line-code that would have taken 10-20 lines of code to write.
3. The uncompressed is more comprehensible with comments and such to explain the code, the minified is just the code without unnecessary characters.
