Different approach for moveLeft() and moveRight()

/** 
     * Moves html token one column to left.
     */
    moveLeft() {
        if( this.columnLocation > 0 ) {
            this.columnLocation -= 1;
            this.htmlToken.style.left = 76 * this.columnLocation;
        }
    }

    /** 
     * Moves html token one column to right.
     * @param   {number}    columns - number of columns in the game board
     */
    moveRight(columns) {
        if( this.columnLocation < columns - 1 ) {
            this.columnLocation += 1;
            this.htmlToken.style.left = 76 * this.columnLocation;
        }
    }

I simply multiplied the columnLocation with 76 to set the correct position. Note that it is important to update the columnLocation BEFORE multiplying or else your token moves in weird ways.
