        var colors2=colors.concat("white","black");
        var colors3=colors2.concat(["brown"]);
        var colors4=colors3.concat("green",["tan"]);
        var colors5=colors4.concat("syan",["gray",["yellowgreen"]]);

        var colors6=colors5.slice();
        var colors7=colors5.slice(,);
        var colors8=colors.slice(-,-);
        var colors9=colors.slice(-);
        var colors10=colors.slice(-,-);
        var colors11=colors.slice(-,-);


        var colors12=colors.splice(,);
        var colors13=colors.splice(,,"pink","stone");

        document.write("+++++concat()方法+++++++");
        document.write("<br>");
        document.write(colors);
