| SPC058990: Object constructor takes no arguments | Object constructor takes no arguments | JavaScriptFile | Warning |
| SPC058994: Consider replacing maximum numeric literal with Number.MAX_VALUE | Consider replacing maximum numeric literal with Number.MAX_VALUE | JavaScriptFile | Warning |
| SPC058995: Consider replacing minimum numeric literal with Number.MIN_VALUE | Consider replacing minimum numeric literal with Number.MIN_VALUE | JavaScriptFile | Warning |
| SPC058999: Unused label | Unused label | JavaScriptFile | Warning |
