Global variables, on the other hand, are declared outside of any function and can be accessed from any part of the program, persisting throughout its execution.
5 Απρ 2018 · What is Local-Variable Type Inference? This new feature will allow you to declare and initialise local variables with var, rather than specifying a type. This feature is already a part of most other statically typed languages (It has been in C# since 2007). For example, with Java 9 or earlier your code might look like this:
Difference between global variables and local variables.
