Grammatical fix - Reduce Object question

[jafarlow]

Describe the bug
In the second bullet point of the explanation, there are three updates which will facilitate reading.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://quiz.typeofnan.dev/reduce-object/
2. Click on any wrong answer to generate the explanation.
3. Scroll down to the explanations, bullet point 2.
4. See error

Expected behavior
There is a grammatical error with a missing period between two sentences. There should be one between "element" and "In".

You've established that any reference to pieces of the code are displayed in code block syntax (I think that's how to describe it). In this bullet point, "agg" and "el" should be displayed as such.
