-You have been declaring your variables with the `var` keyword. However, in modern JavaScript it is best practice to use the `let` keyword instead. This fixes several unusual behaviors with `var` that can make your code difficult to debug.
-
-Change all of your `var` keywords to `let`.
-

-Use the `let` keyword to create a variable named `currentWeapon`. Don't assign it a value yet.
+The next step is to create a variable called `currentWeapon`.

-Notice that you already have a `currentWeapon` variable elsewhere in your code. Since you are using the `let` keyword instead of `var`, the new `currentWeapon` is scoped only to this `if` statement. At the close of the `if` statement, the old `currentWeapon` will be used again.
+Notice that you already have a `currentWeapon` variable elsewhere in your code. Since this new `currentWeapon` variable will be inside an `if` statement, it will be scoped only to that block of code. 
+
+Scope is the term used to describe where a variable can be accessed. If a variable is declared inside a block of code, it is only accessible to the code inside that block. This is called block scope. 
+
+```js
+let num = 1;
+if (num === 1) {
+  let num = 2; // this num is scoped to the if statement
+  console.log(num); // expected output: 2
+}
+console.log(num); // expected output: 1 (the global variable)
+```
+
+Use the `let` keyword to create a variable named `currentWeapon`. Don't assign it a value yet.

 You should not use `let` or `const`.

 ```js
-assert.notMatch(fightSlime.toString(), /let|const|var/);
+assert.notMatch(fightSlime.toString(), /let|const/);
 ```

 You should call the `goFight` function.
