Unable to pass the contents of fetched data using CORS proxy to another function

[IshaGupta18]

To fetch data from a remote file #35 , I had to implement a CORS proxy for it, and it is able to fetch the data from the remote CSV file, however, I am unable to pass it on to another function, but just print it in the console. #42 has the code for it, I have left a review in the PR against the code snippet. Let's resolve this really quickly

	handleFileSelectremote(val){
	const proxyurl = "https://cors-anywhere.herokuapp.com/";
	const url = val;
	fetch(proxyurl + url)
	.then(response => response.text())
	.then(contents => console.log(contents))
	.catch(() => console.log("Can’t access " + url + " response. Blocked by browser?")) ;
	console.log(this.csvFile,"remote file");
	}

 handleFileSelectremote(val, callback){ 
     const proxyurl = "https://cors-anywhere.herokuapp.com/";  
     const url = val; 
     fetch(proxyurl + url) 
     .then(response => response.text()) 
     .then(contents => callback(contents))
     .catch(() => console.log("Can’t access " + url + " response. Blocked by browser?")) ; 
 } 

@IshaGupta18 Try doing this. Also, do we think that it might be more useful to pass the error object inside the catch arrow fn, for a better description (since there could be scenarios where the request fails and isn't actually blocked by the browser)?
