The only difference is that the statement will initialize any declared variables without a value to undefined. In both examples, you are declaring a variable. If you assign a value to a variable without the statement, it will go down the scope chain looking for declared variables, eventually falling back to the global object.
To initialize means assigning an initial state to the object before it is used. This initialization can be part of the instantiation process, in that case values are explicitly assigned to object attributes in the constructor of the object.

How to initialize a struct in accordance with C programming language ...
Here i can be "initialized" from two possible locations, by simple assignments. Because of that, if i was an array, you can't use the special array initializer shorthand syntax with this construct. So basically "initialization" has two possible definitions, depending on context: In its narrowest form, it's when an assignment is comboed with declaration. It allows, among other things, special ...
The third way of initializing is useful when you declare an array first and then initialize it, pass an array as a function argument, or return an array. The explicit type is required.
