Lab: Functions in JavaScript

Estimate Completed Time: 30-60 minutes

Overview: You are working as a junior developer at a company that builds tools for managing personal budgets. Your task is to create a set of basic functions to perform common calculations related to budgeting. This lab will help you practice defining and using functions in JavaScript.

Tools and Resources:

• VSCode
• GitHub repository https://github.com/learn-co-curriculum/phase-0-js-functions-lab.git
• Refer to previous lessons on JavaScript functions if needed

Instructions:

1. Fork and Clone the Repository:

   • Fork the provided GitHub repository to your own account.
   • Clone your forked repository to your local machine.

2. Navigate to the Project Directory:

   • Open a terminal and navigate to the project directory where you cloned the repository.

3. Create Functions:

   • Function 1: calculateTax

     • Create a function named calculateTax that takes a single parameter, amount, representing a monetary value.
     • The function should calculate a 10% tax on the amount and return the tax value.

   • Function 2: convertToUpperCase

     • Create a function named convertToUpperCase that takes a single parameter, text, which is a string.
     • The function should convert the string to uppercase and return the result.

   • Function 3: findMaximum

     • Create a function named findMaximum that takes two parameters, num1 and num2, which are numbers.
     • The function should return the larger of the two numbers.

   • Function 4: isPalindrome

     • Create a function named isPalindrome that takes a single parameter, word, which is a string.
     • The function should return true if the string is a palindrome (reads the same forward and backward), and false otherwise.

   • Function 5: calculateDiscountedPrice

     • Create a function named calculateDiscountedPrice that takes two parameters: originalPrice and discountPercentage.
     • The function should calculate and return the price after applying the discount. For example, if originalPrice is $100 and discountPercentage is 20, the function should return $80.

4. Test Your Functions:

   • Run the tests provided in the repository to ensure your functions work as expected. The tests will check the correctness of your implementations.

5. Submit Your Work:

   • Once your functions are implemented and pass all tests, commit your changes and push them to your forked repository on GitHub.

Submission and Grading Criteria:

• Submission Format: Submit a link to your GitHub repository.
• Grading Criteria:
  • Correct implementation of each function (calculateTax, convertToUpperCase, findMaximum, isPalindrome, and calculateDiscountedPrice).
  • Functions should handle typical input values correctly.
  • Code should be clean and follow JavaScript conventions.
