JavaScript Creating Unchanging Variables With const

So basically, writing const makes the variable name within a function a local variable?

The inner variable is said to "shadow" the outer one. Both exist, but because they have the same name only the inner one is accessible to the inner code. And this is not unique to "const", shadowing occurs just the same with variables declared with "var" or "let".

You are correct that if you use different names then both variables can be accessed from the inner code.
