 Ideally we'd go and discuss the problem with those who are about to use the resulting data. For their purposes, is the fact that some prices are just minimum prices important? What would be the most useful representation of the range for them? Maybe they'd tell us that it's okay if we just remove the `From` prefix?
 
 ```js
-const priceText = price.text().replace("From ", "");
+const priceText = $price.text().replace("From ", "");
 ```
 
 In other cases, they'd tell us the data must include the range. And in cases when we just don't know, the safest option is to include all the information we have and leave the decision on what's important to later stages. One approach could be having the exact and minimum prices as separate values. If we don't know the exact price, we leave it empty:
 
 ```js
 const priceRange = { minPrice: null, price: null };
-const priceText = price.text()
+const priceText = $price.text()
 if (priceText.startsWith("From ")) {
     priceRange.minPrice = priceText.replace("From ", "");

 We call the operation of removing whitespace _trimming_ or _stripping_, and it's so useful in many applications that programming languages and libraries include ready-made tools for it.

 We need to remove the dollar sign and the decimal commas. For this type of cleaning, [regular expressions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_expressions) are often the best tool for the job, but in this case [`.replace()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace) is also sufficient:
