error:

1. 03 - What's Your Name? should complete all tasks Task Create test-helpers for all tests #2 - don't greet user if name wasn't provided Should display welcoming message if user didn't provide their name:

 AssertionError: If user didn't enter the name (`this.state.name` length is 0), show "Hey there. Enter your name.". See the hint in task's description.
 + expected - actual
 -Hey there. Enter your name
 +Hey there. Enter your name.

looks like the same;why ?
my code :

render() {
var howdy = "Hello " + this.state.name;
if(this.state.name.length<=0)
howdy ='Hey there. Enter your name';

return (
 <div>
 <p>{howdy}</p>
 <input type="text" name="name" onChange={this.onNameChange} />
 </div>
);

}
