How are global variables accessed within functions?
Global variables in JavaScript can be accessed within functions using the scope chain mechanism. The scope chain is a hierarchical structure that determines the accessibility of variables in JavaScript. When a function is executed, a new scope is created, and this scope has access to variables defined within its own block, as well as variables
