Desafio intermediário de JavaScript:

Imagine que estou apostando corrida de carrinhos Hot Wheels com meu filho, e preciso de uma função JS pra registrar o placar. 

O problema é que eu só tenho o Internet Explorer de 2010 pra fazer essa função, então tenho algumas regras

- não posso utilizar let nem const
- não posso manipular o escopo externo
- não posso utilizar nenhum mock

/*
	Unfollow (stop following) those people who are not following you back on Twitter (or unfollow everyone if desired).
	
	This will work for new Twitter web site code structure (it was changed from July 2019, causing other unfollow-scripts to stop working).
	
	Instructions:
	1) The code may need to be modified depending on the language of your Twitter web site:
		* For English language web site, no modification needed.
		* For Spanish language web site, remember to set the 'LANGUAGE' variable to "ES".
		* For another language, remember to set the 'LANGUAGE' variable to that language and modify the 'WORDS' object to add the words in that language.
