Please help me. I don't know what's the problem.
function testIsnan(x){ if(isNaN(x)){ return “this is a text”; } else if (!isNaN(x)){ return “this is a number”; } else{ return “Please try again”; }
} ;
testIsnan(‘moh’);
This is my code. it’s working but there is an error message appearing to me “Oops, try again. Make sure your if/else if/else statement returns a string when the function input isn’t a number.”
I don’t know what’s the problem. Please I need your help and tell me what should I do.
