Geometric constructions with JessieScript

The JavaScript code

<jsxgraph width="500" height="400" box="box">
        var cons1, cons2;
        board = JXG.JSXGraph.initBoard('box', {grid:true, originX: 50, originY: 300, unitX: 50, unitY: 50, axis:true});

        cons2 = board.construct("J(7,4);[GJ[;K(8,4);]GK[;L(2.4|5);f=[AC];k1=k(C,0.5);C_1(4|4);l_2=[BC]");
        
        cons1.points[0].setProperty({face:'diamond',size:7,strokeColor:'#8B2252',fillColor:'#8B2252'});
        cons1.circles[1].setProperty({strokeColor:'#BA55D3'});
