Exploring the Depths of Javascript Variable Scope

bar: function () {
  var cValue = false;

  car(4, function () {
    cValue = true;
    if (cValue)
      alert("cvalue is true 1");
  });

  if (cValue)
    alert("cvalue is true 2");
}

car: function (val, fn) {
  fn();
}

I have encountered a similar issue in my code and I am unable to trigger the second alert. Can you spot any potential problems in the code provided above?

Answer №1

Your usage of the label in the function statement is incorrect. Instead of

boo: function (val, fn) {
  fn();
}

You should use it like this:

function boo(val, fn) {
  fn();
}

A similar issue exists with foo. This will result in a SyntaxError and halt the script execution. Thankfully, it can easily be identified by checking the console.
