how to get first letter of a string in ajax response

[shadd]

i have this php script:

    $result='Osucess'
echo $result;

i have this jquery ajax:

 	$("#add_sub").submit(function (e) { 
		e.preventDefault();
		var formDatax = new FormData($('#add_sub')[0]); 
$.ajax({
				type: "POST",
				url: 'answers.php',
				data:  formDatax,

			    //Options to tell jQuery not to process data or worry about content-type.
                cache: false,
                contentType: false,
                processData: false,
			success: function(data){

				
				if(data.charAt(0) ==="O"){
					alert(data);
					
				}else{
					alert("failed");				}
				
			}	
				
		});
});

but it does not work at all.what is the problem??

I'd start by checking what data contains with

console.log(data)

sole.log(data)

it contains "Osucess" but the if tatements do not work out

And when i try console.log(data[0]);

it shows nothing at all.

this is what i did to get it

var str= data ;
                let removedSpacesText = str.split(" ").join("");
                alert(removedSpacesText);
                alert(removedSpacesText[0]);

and it worked
