**Global scope**: Variables defined globally (i.e. not inside a block or function) are part of the global scope and can be accessed from anywhere in the code. When declared in the global scope, `var`, `let` and `const` behave the same in terms of scope.
**Local scope**: Variables defined inside a block or function can only be accessed from the block or function where they were defined, as well as nested local scopes. When declared inside a block scope, `var` will be available but `undefined` in outer scopes, while `let` and `const` will not exist in outer scopes. When declared inside a function scope, `var`, `let` and `const` will all be non-existent in outer scopes.
