Fix variable name in citizen-engagement.js

[tamara-snyder]

Dependency

• Refactor JavaScript: Move script from citizen-engagement.html to external file #2480

Overview

We need to fix a typo in a variable name so that we can reuse it reliably.

Details

As developers, it is important to write our JavaScript variable names carefully so that we don't mistakenly declare new variables that pollute the global namespace. In this issue, we will fix a variable name typo in assets/js/citizen-engagement.js in order to prevent a global variable from being declared later in the file.

Action Items

• In line 4 of assets/js/citizen-engagement.js, change let currentDropown; to let currentDropdown;
• Check that the Citizen Engagement page still functions as expected
• Create a pull request for this issue according to the instructions found in the pull request section of CONTRIBUTING.md

Resources/Instructions

• Citizen Engagement page
• The file you'll be editing: assets/js/citizen-engagement.js
• CONTRIBUTING.md
• Although the code in citizen-engagement.js is technically fine, here's a brief explanation as to why declaring variables without let, const, or var isn't best practice.
