Eslint Unknown Rule

A simple eslint rule that guards against the use of the unknown keyword

The following example would trigger the rule:

const foo: unknown = 2

Note: this rule ignores unknowns that are error parameters in try catch blocks. For instance, the following is considered valid:

try {
  console.log('Eslint is cool')
} catch (e: unknown) {
  console.log(e)
}
