WGU D276 DEBUGGING UPDATED EXAM
(LATEST UPDATE) |VERIFIED 100%
• What is debugging?
o Debugging is the process of resolving either unintended or unexpected
behaviors by examining code as it runs.
|
• What are the two main types of HTML errors you will encounter?
o Syntax Errors: Errors in the interpretation of your code, usually resulting in
nasty exceptions or wild behavior.
▪ Ex: Having a typo in the call “Console.log(“Hello World”)” would be a
syntax error.
o Logic Errors: Errors made by the programmer in the logical control flow that
introduce unexpected behavior
▪ Ex: Having a for-loop run 4 times instead of 5, leading to early exits and
incomplete data checking.
• What is the W3C markup validation service?
o A free online code checker that will determine what errors may occur and
help you resolve them.
• How do you access the DevTools?
o Usually by pressing F12, however you can right-click and say “Inspect” or
get there through settings menus as well.
• What is the rules view?
o The Rules View shows you what CSS rules are applied and from where:
, • How do you add a new property?
o In the element.style section, you can click and it will allow you to enter new
properties and values, which change the page in real time.
• What are the three components of the debugging process?
o Find: Discover the unexpected behavior you want to change
o Identify: Determine what is causing the unexpected behavior
o Fix: Implement a fix that will prevent the unexpected behavior from
happening again.
• What is the Chrome DevTools?
o Chrome Devtools are a suite of tools designed to help every aspect of the web
development process
• What programming languages can the Chrome DevTools help debug?
o HTML, CSS, and Javascript
