Rodolfod1.Code-Quiz

========================================

My Code Quiz

deployed application can be found at

https://rodolfod1.github.io/Code-Quiz/index.html

My approach to this project (web API):

• This code was designed to prompt to the user a series of questions with multiple choice answers.
• Questions and answers are pulled from an object to make the question evaluation easier to understand.
• Questions are displayed randomly every time the user clicks the "Take the Quiz" button.
• Screens showing the questions, the score submission and the leadBoard with the top 3 scores are dynamically generated,using the querySelector method for DOM manipulation.
• Scores are kept an object on the local storage; then they are parsed to an array for operations and manipulation.
• 12 Functions are deployed to carryout all the different user selections.
• A set of loops, conditionals and 4 event listeners supports user interactivity.
• Bootstrap 4.0 was used for fast set up and management of cards tables and navbar
• A simple but bold CSS was added and though on make it user neutral.

** About the application **

• When the page loads:

  • The user is presented with a nav bar where it can select the options of reading instructions for the quiz, view the high scores , or take the quiz.

  • This app was developed with mobile first mind set, so the collapsed Nav bar will include a label for the main menu button.

    • This is an example of the page when it loads

    • When the user clicks on "View instructions" the following is displayed:

    • A Leaders Board view is available for the user to select by clicking on "View High Scores" label.

• Mobile first approach:

• Responsive application using bootstrap 4.0
  • Here is an example of the top three high scores on an iPhone X:

• To run the application:

  • The user needs to click the "Take the Quiz" button.

    • The application will start displaying the questions and choices randomly so the user will have a different order every time they restart the quiz

    • A timer will start showing the seconds left .

    • 2 minutes are set on the timer.

    • Every wrongly answered question will deduct 30 seconds out of the timer.

    • The quiz finishes when the user have gone thru all the questions or de timer is depleted.

    • Here it is the example of the quiz and timer deployment:

• When the quiz ends:

  • Once any of the conditions, either the questions OR the timer are depleted the user is prompted with a form which includes the score and a submission input for the scores to be recorded for further usage on the leaders board.

    • Image of the submission form:

• Style:

• Html was designed using Bootstrap 4.0 and CSS designed simpler to adapt a sober and bold style.

• About Javascript.

• Simple variables were used to gain efficiency on coding and debugging.

• Balance between global and local variables to facilitate and easier analysis and debugging.

• Functions, LocalStorage, JSON , Objects and Events managers are deployed on this project.

• Questions and answers are arranged within an object for easier addition of elements

  • Example of the questions object for easy addition of elements: I

  • Example of the localStorage management:

*This Project contents:
