lexical scoping javascript

A lexical scope in JavaScript means that a variable defined outside a function can be accessible inside another function defined after the variable declaration. But the opposite is not true; the variables defined inside a function will not be accessible outside that function.

lexical scoping in javascript

// Define a variable in the global scope:
const fullName = "Oluwatobi Sofela";

// Define nested functions:
function profile() {
  function sayName() {
    function writeName() {
      return fullName;
    }
    return writeName();
  }
  return sayName();
}
