    <script>
        //length：获取字符串长度
        var str='my name is very';
        console.log(str.length);//15
        //console.log('沙漠"＋‘骆驼");
        //只要有字符串和其他类型拼接，最终结果都是字符串类型
        console.log( '即兴'+'小索奇');//字符串-即兴小索奇
        console.log('天天'+true);//天天true
        console.log(12+12);//24
        console.log('12'+12);//1212
        //分享小技巧————输入console.log( '即兴'+'小索奇')时可以先输入console.log(''++ '')
        //简记引引加加''++''
        console.log( '即兴'+plus+'小索奇');
