This is not the same as dynamically
typing, as the data will still need to be of a consistent type. When the compiler scans your code, it
attempts to ensure that the type assigned to the variable does not deviate throughout its lifetime.
Type inference will have a great impact on your applications when you start using functions. You are
introduced to functions in Chapter 4 , ??? Controlling the Flow of Information. ???
Enter this code into a new file and save it as TypeInference.hx :
class TypeInference
{
public static function main()
{
var myVar = 10.5;
trace(myVar);
}
}

Now compile and run this example. You should see the content of myVar displayed in the command
window. Now modify the code to include these new lines:
class TypeInference
{
public static function main()
{
var myVar = 10.5;
trace(myVar);
myVar = ???The quick brown fox.???;
trace(myVar);
}
}
When you compile this example, you should be presented with an error that states the following:
TypeInference.
