Converting Fahrenheit to Celsius Please create a JavaScript application, named as “convert_temps.html”, that converts Fahrenheit temperatures to Celsius temperatures: Use the prompt() method to ask user to input a Fahrenheit value. Convert Fahrenheit to Celsius, first subtract 32 from the Fahrenheit temperature. Then, multiply that result by 5/9. (That is c = (f-32) * 5/9). Add data validation to the application so it won’t do the conversion until the user enters a Fahrenheit temperature between -100 and 212. If the entry is invalid, an alert dialog box should be displayed. Add a loop to the code so the user can do a series of calculations without restarting the application. To end the application, the user must enter 999 as the temperature.
