JQury
- jQuery offers a simple way to achieve a variety of common JavaScript tasks quickly and consistently, across all major browsers and without any fallback code needed.
- jQuery doesn’t do anything you cannot achieve with pure JavaScript. It is just a JavaScript file but estimates show it has been used on over a quarter of the sites on the web, because it makes coding simpler.
- The
• htm 1 ()and• text ()methods both retrieve and update the content of elements. *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. - The
.animate()method allows you to create some of your own effects and animations by changing CSS properties.
6 Reasons for Pair Programming
How does pair programming work?
- While there are many different styles, pair programming commonly 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.
- Handling the “mechanics” of coding, the Driver manages the text editor, switching files, version control, and—of course writing—code.
- The Navigator uses their words to guide the Driver but does not provide any direct input to the computer.
- The Navigator thinks about the big picture, what comes next, how an algorithm might be converted in to code, while scanning for typos or bugs.
- The Navigator might also utilize their computer as a second screen to look up solutions and documentation, but should not be writing any code.
## Why pair program?
- Greater efficiency : when two people focus on the same code base, it is easier to catch mistakes in the making.
- 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 .
- Work environment readiness .
