@ -427,6 +427,7 @@ The "integer property" term here means a string that can be converted to-and-fro
So, "49" is an integer property name, because when it's transformed to an integer number and back, it's still the same. But "+49" and "1.2" are not:
```js run
// Number(...) explicitly converts to a number
// Math.trunc is a built-in function that removes the decimal part
alert( String(Math.trunc(Number("49"))) ); // "49", same, integer property
alert( String(Math.trunc(Number("+49"))) ); // "49", not same "+49" ⇒ not integer property
