Hope this helps You have whitespaces where i have written underscores

__

, that is why your strings are not equat. Either remove the whitespaces, or use .trim() fuction on your innerHTML to remove the whitespace.

wish help you to fix your issue I'm getting data from a MySQL database using PHP and then echoing it out to the page. I encode the string using htmlentities() to avoid XSS problems. I need to compare the text that a user writes in a textbox with the data echo'd out, but I've run into a problem. Suppose the data in the database is le beau-frère, then the data that get's echo'd out looks like this: , I would use innerText - it will convert the htmlentities data from
code :
le beau-frère
le beau-frère
<div id="foo"></div>

<script type="text/javascript">
document.getElementById('foo').innerHTML = 'le beau-fr&egrave;re';
var savedData = document.getElementById('foo').innerText;
</script>
How do I compare the String returned from a function to another String variable in Javascript

it should still fix some issue Yet another edit. After your comment I worked it out. Please see the fiddle. https://jsfiddle.net/hc05fhxr/9/
the code is as follows and you can change it however you like. But it returns true for a match and returns the mismatches as asked. The reason it always used to return false was because the function diffString() adds an unneccesary new line in the returned result. I have basically just removed that and run the test.
code :
    var strng = diffString("asdfHello","Hello");
if(strng[-1]==/\n/){strng = strng.slice(0,-1)}

if(strng===" Hello"){
    alert(true);
}else{
    alert(strng);
}

wish of those help Based on your explanation I have created an example of what you require. In this example of code I have created a function that will accept two strings, they will be split by any non-word character and then compared regardless of the word order in the string. If strings are the same, that is contain the same words disregarding the word order, it will return true.
code :
let string1 = "this is the string";
let string2 = "string is the this";

function findMatch( string1, string2 ) {
	//split by any non-word character, anything that is not
        //a-z, A-Z, 0-9 ( including the _ character )
	let splitPattern = /\W/;
	let split1 = string1.split( splitPattern );
        let split2 = string2.split( splitPattern );
	
    //traverse string1 array 
	for ( let i = 0; i < split1.length; i++ ) {
           let checkForMatch = false;
          //traverse string2 array
  	  for( let j = 0; j < split2.length; j++ ) {
    	    if ( split1[ i ] === split2[ j ] ) {
              checkForMatch = true;
              break;
            }
          }//inner for
    
    //if match not found in one itteration, strings do not
    //match and false should be returned
    if ( !checkForMatch ) {
    	return false;
    }
  }//outer for
  
  //else it matches so return true
   return true;
 
}//end findMatch

console.log( findMatch( string1, string2 ) );
