What happens when I name a local variable the same thing as an existing global variable??

If I globally declare a variable and then use same name of the variable in a function which could be local variable. Then want will happen??

You'll hide the global variable due local scope is primary.

Within a class you can specify the scope with this.* , or base.* (C#).

Ok, but what happen when you declare the variable globally and you the name of variable as a parameter in a function. Suppose var balance = 10500; and function steal(balance, amount) { if(amount < balance) { balance = balance - amount; } return amount; } var amount = steal(balance, 1250);
