refactor: use "for of" loop in the plugin folder#896
Conversation
Prefer the use of for-of loop over the standard for loop where possible. This simplifies the syntax and make the code easier to read.

ℹ️ Converted to Draft, I am going to add some tests |

nitpick: rename dic to cellStates for clarity. We are not using a Dictionary type (which has been removed) and it is clearer to name the variable with the context it holds instead of using a name related to a type.
NOTE: this applies to all tests in this file

| * var nodes = []; | ||
| * var codec = new Codec(); | ||
| * model.addListener(mxEvent.CHANGE, function(sender, evt) { |

nitpick: mxEvent does not exist, this is a mxGraph value

nitpick: rename parameter, see remark about the dic variable

suggestion: use a filter method on the original array (add tests before doing the refactoring)

| for (let i = 0; i < childCount; i += 1) { | ||
| count += this.addStates(cell.getChildAt(i), dict); |

todo: add tests here and for all methods where using direct loop instead of using cell.getChildCount and cell.getChildAt

Add afterEach to destroy the graph and release resources
