Challenge: Grocery Store

Suppose you run a small grocery store with daily expenses of $2000. If your daily revenue is less than $2000, you're operating at a loss; otherwise, you're turning a profit. Let's craft an if/else statement to reflect this situation.

Task

Set up a conditional statement to determine if the revenue variable is below 2000.

If it is, display the message "We're operating at a loss!".
Otherwise, display the message "Everything is good!".

Please refrain from altering the revenue value.
