Boolean variable name suggestion

For a boolean variable, the name should usually be a predicate, or a statement that may be true or false. It's a good practice to include a verb in your variable name which suggests the state or condition the boolean is representing. Here are some suggestions, depending on the usage:

isConnected
hasItems
canSave
shouldDisplay

Remember, choosing a good and meaningful name for variables is very important as it makes your code easier to understand and maintain.
