The JavaScript code

JessieScript is not longer actively delevoped. Instead, the focus is on the programming language JessieCode. As a consequence, JessieScript is not contained in jsxgraphcore.js anymore. If you want to use JessieScript, you have to load the file jessiescript.js from the JSXGraph sources or the file https://jsxgraph.org/distrib/JessieScript.js after loading jsxgraphcore.js 

var board, construction = [];
board = JXG.JSXGraph.initBoard('box', {grid:true, boundingbox:[-1,6,11,-3], keepaspectratio:true, axis:true});

function construct() {
    var t = document.getElementById('input').value;
    board.suspendUpdate();
    construction.push(board.construct(t));
    board.unsuspendUpdate();
}

function clearAll() {
    JXG.JSXGraph.freeBoard(board);
    board = JXG.JSXGraph.initBoard('box', {grid:true, boundingbox:[-1,6,11,-3], keepaspectratio:true, axis:true});
}
