| 1. What is scope? | |
| Scope is where the variable can used. A variable declared globally means that it can accessed everywhere including in local scopes | |
| such as functions or conditional statements. | |
| 2. Why are global variables avoided? | |
| Global variables will overwrite other variables with the same binding name in local scopes such as functions. This will lead to | |
| unintended results. To avoid this, inside the function, redeclare that binding name so that it is set in that local environment. |
