A simple solution to this problem is to wrap any code that you don't want in the global scope in an immediately-invoked function expression (IIFE). All the variables assigned in the function's scope are deallocated when the function ends:

(function() {

    // Put your code here...

})();

[Update]

In ES6 you can use blocks (so long as you use let instead of var):

{

    // Put your code here...

}
