Interactive Temperature Converter

Overview and Objectives

In this lab, learners will apply JavaScript operators (assignment, arithmetic, logical, comparison, and string operators) along with user interaction techniques to build a simple temperature converter. By the end of this lab, learners will be able to:

• Use prompt() to obtain user input.
• Convert input strings to numbers.
• Apply arithmetic operators to convert Celsius to Fahrenheit using the formula:
  Fahrenheit = (Celsius * 9/5) + 32
• Use conditional statements to validate user input.
• Output results clearly using alert() or console.log().
• Write clean, well-documented code that demonstrates best practices.

Tasks and Instructions

Task 1: Create the Temperature Converter Script

1. File Creation:

   • Create a JavaScript file named tempConverter.js.

2. User Input:

   • Use the prompt() function to ask the user to enter a temperature in Celsius.
     Example:

     let celsiusInput = prompt("Enter temperature in Celsius:");

3. Input Validation and Conversion:

   • Convert the input to a number using Number() or the unary plus (+) operator.
   • Validate that the input is a valid number. If it is not, display an error message using alert() and terminate further execution.

4. Perform Calculation:

   • Use arithmetic operators to compute the Fahrenheit equivalent using the formula:

     let fahrenheit = (celsius * 9/5) + 32;

   • Use assignment operators appropriately during the calculation.

5. Display the Result:

   • Display the final result in a formatted message using either alert() or console.log(). For example:
     "25°C is equivalent to 77°F"
   • Consider using template literals for clearer formatting.

6. Enhancements:

   • Provide additional user interaction, such as asking if the user wants to perform another conversion.
   • Use additional error handling for edge cases (e.g., empty input).

Task 2: Test Your Script

• Run your script in a browser (using an HTML file that includes tempConverter.js) or using an online JavaScript editor.
• Verify that valid numeric input produces the correct Fahrenheit conversion.
• Verify that non-numeric input triggers an error message.

Submission Criteria

The following should be included within a GitHub repository, and submitted via Canvas:

• Files/Links:

  • Submit the tempConverter.js file.
  • If using an online editor, include a link to your project.

• Evidence of Output:

  • Provide a screenshot or text log showing the code execution with both valid and invalid inputs.

• Error-Free Code:

  • Ensure the script runs without syntax or runtime errors.
