How do I access the token id from within the Space class?

Really confused as to how I access the id of the current token dropped into the space, when the Space class doesn't have references to any of the other Classes. The other classes have references to other classes by way of using someVariable = new Board(); or whatever the case may be, but I don't want the "mark" method to create a NEW object, do I?

I feel like this would be much easier achieved by just setting the "token" value of the space the token was dropped into by adding in the playToken90 method from the previous step.

whateverTheChosenSpaceWas.token = this.activePlayer.activeToken.id;

You don't. The token should be passed as a parameter to the mark() method. That's what's indicated in the JDoc by the @param line:

* @param {Object} token - The dropped token

I thought similar to you so wanted to test it out to make sure I was setting the space to be the current token (which I think is a bit more than what this step asks for but I always like to make sure I have as full an understanding of the code as possible before moving on.

In Game.js

    let spaces = this.board.spaces;
    let activeToken = this.activePlayer.activeToken;
    let currentColumn = spaces[activeToken.columnLocation];

    for (let i = 5; i >= 0; i--) {
      if (currentColumn[i].token == null) {
        const targetSpace = currentColumn[i]

        this.ready = false;
        activeToken.drop(targetSpace)
        // below is the line that takes the space, calls the mark method, 
        // and sends the method the active token
        targetSpace.mark(activeToken)
        break
      } 
    }
  }

In Space.js

  mark(activeToken) {
    // receives the activeToken we sent from Game.js
    // and sets the Space object's token property
    this.token = activeToken;
    // I like to console.log the results to make sure it works!
    console.log(this.token)
  }
