jQuery

It is a javascript library.
You can use it as an object and then add methods for it.
Older browsers do not support the latest methods for selecting elements.
jQuery’s motto is “Write less, do more,” because it allows you to achieve the same goals but in fewer lines of code than you would need to write with plain JavaScript.
You can select either one element or multi elements in jQuery.
There is no need to use a loop when a selector returns multiple elements, you can update all of them using the one method.
If you want to use more than one jQuery method on the same selection of elements, you can list several methods at a time using dot notation to separate each one.
The html () and text () methods both retrieve and update the content of elements.
html() : This method gives every element in the matched set the same new content.
replaceWith(): This method replaces every element in a matched set with new content.
text(): This method gives every element in the matched set the same new text content.
remove(): This method removes all of the elements in the matched set.
Inserting new elements involves two steps: 1: Create the new elements in a jQuery object 2: Use a method to insert the content into the page
before() : This method inserts content before the selected element(s) .
prepend() : This method inserts content inside the selected element(s), after the opening tag.
after() : This method inserts content after the selected element(s).
append() : This method inserts content inside the selected element(s),before the closing tag.
You can create attributes, or access and update their contents, using the following four methods.
The css () method lets you retrieve and set the values of CSS properties.
jQuery allows you to recreate the functionality of a loop on a selection of elements, using the each () method.
The on () method is used to handle all events.
Every event handling function receives an event object.
When you start using jQuery, the effects methods can enhance your web page with transitions and movement.
The animate() method allows you to create some of your own effects and animations by changing CSS properties.
When a page loads jQuery from a CDN, you will often see a syntax starts with a <script> tag that tries to load the jQuery file from the CDN.
The position of <script> elements can affect how quickly a web page seems to load.

6 Reasons for Pair Programming

Improving the quality, you can use iterative loops, code reviews, fast feedback and error checking and linting.
Pair programming is the practice of two developers sharing a single workstation to interactively tackle a coding task together.
Pair Programming involves two roles: the Driver and the Navigator.
- The Driver is the programmer who is typing and the only one whose hands are on the keyboard.
- The Navigator uses their words to guide the Driver but does not provide any direct input to the computer.
Pair Programming use skills of developers explain out loud what the code should do, listen to others’ guidance, read code that others have written, and write code themselves.
Greater efficiency: It is a common misconception that pair programming takes a lot longer and is less efficient.
Engaged collaboration: When two programmers focus on the same code, the experience is more engaging and both programmers are more focused than if they were working alone.
Learning from fellow students: Working with a teammate can expose developers to techniques they otherwise would not have thought of.
Social skills: When working with someone who has a different coding style, communication is key.
Job interview readiness: The current employee and an applicant will carry out exercises together, such as code challenges, building a project or feature, or debugging an existing code base.
Work environment readiness: Code Fellows graduates who are already familiar with how pairing works can hit the ground running at a new job, with one less hurdle to overcome.
