// Error = An Object that is created to represent a problem that occurs
// Occur often with user input or establishing a connection
// try { } = Encloses code that might potentially cause an error
// catch { } = Catch and handle any thrown Errors from try { }
// finally { } = (optional) Always executes. Used mostly for clean up
// ex. close files, close connections, release resources
try{
const dividend = Number(window.prompt("Enter a dividend: "));

if(divisor == 0){

}

throw new Error("Values must be a number");
}
const result = dividend / divisor;
console.log(result);
}
catch(error){
console.error(error);
}
finally{
console.log("This always executes");
}
console.log("You have reached the end!");
