#JavaScript closures part 2 😁: - According to MDN, at first glance, it may seem unintuitive that this code still works. In some programming languages, the local variables within a function exist only for the duration of that function's execution. Once setLocation() has finished executing, you might expect that the country variable would no longer be accessible. However, because the code still works as expected, this is obviously not the case in JavaScript. - The reason is that functions in JavaScript form closures. A closure is the combination of a function and the lexical environment within which that function was declared. - This environment consists of any local variables that were in-scope at the time the closure was created. In this case, currentLocation() is a reference to the instance of the function printLocation created when setLocation is run. The instance of printLocation maintains a reference to its lexical environment, within which the variable country exists. - For this reason, when currentLocation is invoked, the variable country remains available for use and "France" is passed to console.log. - What are your plans for the #weekend? 🤙
