- `isNaN(value)` converts its argument to a number and then tests it for being `NaN` - `isNaN(value)` converts its argument to a number and then tests it for being `NaN`
- `isFinite(value)` converts its argument to a number and returns `true` if it's a regular number, not `NaN/Infinity/-Infinity` - `Number.isNaN(value)` checks whether its argument belongs to the `number` type, and if so, tests it for being `NaN`
