Project #6: Fetch and display weather based on the userโ€™s location
#SwitchMap Operator
๐˜จ๐˜ฆ๐˜ต๐˜“๐˜ฐ๐˜ค๐˜ข๐˜ต๐˜ช๐˜ฐ๐˜ฏ() method fetches the user's current location. It returns an ๐˜–๐˜ฃ๐˜ด๐˜ฆ๐˜ณ๐˜ท๐˜ข๐˜ฃ๐˜ญ๐˜ฆ. Upon completion, the position coords are updated. Use the ๐˜ฑ๐˜ช๐˜ฑ๐˜ฆ operator to chain operations on the Observable returned by ๐˜จ๐˜ฆ๐˜ต๐˜“๐˜ฐ๐˜ค๐˜ข๐˜ต๐˜ช๐˜ฐ๐˜ฏ(). Use the ๐˜ด๐˜ธ๐˜ช๐˜ต๐˜ค๐˜ฉ๐˜”๐˜ข๐˜ฑ operator to transform the void emission from ๐˜จ๐˜ฆ๐˜ต๐˜“๐˜ฐ๐˜ค๐˜ข๐˜ต๐˜ช๐˜ฐ๐˜ฏ() into an Observable that fetches weather.

Higher-order mapping with RxJS:
- Maps a value (such as an id) to an Observable
- Automatically subscribes and unsubscribes from the inner Observable
- Flattens the result
