Posted 2020-10-11 fm060

<script type="text/javascript">
    var aa = ‘test string‘;
    var bb={
        ta:‘12345‘,
        tb:‘456789‘
    }
    var cc=false
    var ee=function(){
        console.log(8888)
    }
   console.log(typeof aa);  // ‘string‘   
   console.log(typeof 90);  // ‘number‘  
   console.log(typeof bb);  // ‘number‘  
   console.log(typeof cc);  // ‘number‘  
   console.log(typeof dd);  // ‘number‘  
   console.log(typeof ee);  // ‘number‘  
</script>
