What is the proper way to compare enum values using the greater than operator?

Here is an example enum:

enum Status {
  inactive = -1,
  active = 0,
  pending = 1,
  processing = 2,
  completed = 3,
}

I am trying to compare values using the greater than operator in a condition. However, the current comparison always results in false.

const statusValue = 2;
order.status = Status[statusValue];

if (order.status > Status.active) {
  console.log('Order status:', order.status);
}

What would be the correct way to use the greater than operator in this scenario?

Answer №1

It turns out that my error stemmed from mistakenly converting 2 into an Enum key instead of an Enum value.

In addition, Deno incorrectly interpreted the condition as false rather than throwing the expected error:

The operator '>' cannot be used with the 'string' and 'Verbosity' types.

The corrected code functions properly:

const verbosity = 2;

log.verbosity = Verbosity[Verbosity[verbosity]];

if (log.verbosity > Verbosity.normal) {
    log.debug('Verbosity:', Verbosity[log.verbosity]); // Output: Verbosity: veryVerbose
}
