# `git clean` seems to ignore -e option when used with -X so had to replicated its behaviour using `git ls-files`

# only remove ignored files / folders
git clean -Xd # this works fine
git ls-files --directory --others --exclude-standard --ignored | xargs rm -rf # same as above

# only remove ignored files / folders but keep node_modules folder
git clean -Xd -e node_modules # exclude option is ignored
git ls-files --directory --others --exclude-standard --ignored | grep node_modules --invert-match | xargs rm -rf # this works fine

// Both, function declaration and function body are hoisted to top of scope. 

// Outside of scope, hence ReferenceError
console.log(foo); // ReferenceError: foo is not defined

(function () {
  // Declaration and function body got hoisted to top of scope
  console.log(foo); // [Function: foo]
  console.log(foo()); // 'bar'
