Given an array of integers on the
$scope of a controller, write an Angular filter that repeats through the temperatures and displays them on the view in either Celsius or Fahrenheit in the following format:
To do this, you'll need to include a parameter to your filter, either
'F' (indicating a conversion from Celsius to Fahrenheit) or
'C' (indicating a conversion from Fahrenheit to Celsius).
For this exercise, you should implement your filter in the view using the
$filter service. (Although that is a legitimate way to do it).
$scope.temps = [10, 15, 20, 25, 30]
HINT: Degree mark ° = option shift 8.
Sign up for the Dark Sky Weather API @ https://developer.forecast.io/docs and get a personal developer key. Use your local longitude and latitude coordinates to get your local weather.
Display the local temperature on your page. Create a dropdown menu that lets the user choose to see the temperature in Fahrenheit, Celsius, or Kelvin. Create custom Angular filters that change the degree value and symbol/letter that is displayed.
Hint: look up select and ng-options for the drop down menu.
Add an input where the user can enter their ideal temperature. Create a separate filter that calculates and returns the difference between the user's ideal and the current temperate. Display that value elsewhere on the screen.
