How to make this treewalker code with a regular for loop or with a forEach() method?

I don't want to use a `for...of` loop here by principle, because I personally think its syntax confusing.How to make this tree walker with a regular `for` loop, or, alternatively, with a `forEach()` method?

How to make this tree walker with a regular `for` loop, or, alternatively, with a `forEach()` method?I didn't figure that myself because from reading the code I understand that making it either way would require writing it from the ground up but I don't fully understand the code, hence I try to humbly turn to a JavaScript expert.
