Review Summary
I am requesting changes because, while your convertToObject implementation produces the correct result for the given examples, it currently violates two explicit checklist requirements, which are treated as critical.
Critical issues that must be fixed:
- In
src/convertToObject.js, yourreducecallback mutates the accumulator object (e.g.,acc[property.trim()] = value.trim()), which conflicts with the rule: "Don't use iteration methods to modify an already existing array/object. (forEach is exception)." [CHECKLIST ITEM #1]. Instead, havereducereturn a new object on each iteration, for example by spreading the previous accumulator and adding the new key, so you are leveraging the return value rather than mutating the existing object. - The accumulator variable is named
acc, which is considered too generic according to the guideline to avoid vague names likearray,object,arr,obj,result[CHECKLIST ITEM #2]. Rename it to something descriptive of its role, such asstylesObject,stylesByProperty, or similar.
Once you update reduce to build a new object each step and rename the accumulator to a clearer name, your solution will both meet the functional requirements and fully comply with the checklist. The overall parsing logic is solid, so after these adjustments you’ll have a clean and idiomatic implementation.

This use of reduce mutates the existing accumulator object (acc[property.trim()] = value.trim()), which violates checklist item #1: "Don't use iteration methods to modify an already existing array/object. (forEach is exception). These methods return a new array, so you should use it." Consider returning a new object on each iteration instead of mutating acc.

The variable name acc is very generic and conflicts with the spirit of checklist item #2: "Avoid variable namings like array , object arr, obj, result. It will decrease code readability". Use a more descriptive name for the accumulator object (e.g., stylesObject).

Review Summary
I am approving your solution because convertToObject now correctly transforms the styles string into the expected object, with all required key–value pairs parsed and trimmed properly. You use the requested iteration methods (split, map, filter, reduce) without any manual loops, and your reduce callback builds a new object on each step instead of mutating an existing accumulator, which aligns with the checklist guidance [CHECKLIST ITEM #1]. Your variable naming (e.g. stylesObject) is clear and descriptive, avoiding vague names and complying with the naming rules [CHECKLIST ITEM #2]. The chaining of methods on the styles string is neatly formatted and readable, meeting the style and indentation expectations [CHECKLIST ITEM #4]. Overall, the function meets the functional requirements and technical constraints, and there are no critical blockers or missing features. Nice work refining this implementation and addressing the previous issues so thoroughly.
