Get the name of the function from inside the function

Is it possible to get the name of the function from inside the function?
Example:

function myFunction() {

  // console.log the name of this function without knowing/specifying what the name is
  // otherwise console.log('myFunction was called'); is 
  // more obvious (and better supported) than console.log(myFunction.name);
  // console.log(arguments.callee.name); works but not in strict mode and is deprecated
}

Reference:
Function.name
arguments.callee

Update:
From the comments and answers, it appears that the point has been completely missed.
I revised the example to make it clearer.

Update 2:
It seems there is still ambiguity ... here is an example of a debugging process:

function one() {
  console.log(arguments.callee.name + ' was called'); // one was called
  // reset of the code
}

function two() {
  console.log(arguments.callee.name + ' was called'); // two was called
  // reset of the code
}

function three() {
  console.log(arguments.callee.name + ' was called'); // three was called
  // reset of the code
}

function four() {
  console.log(arguments.callee.name + ' was called'); // four was called
  // reset of the code
}

function five() {
  console.log(arguments.callee.name + ' was called'); // five was called
  // reset of the code
}

arguments.callee.name is deprecated and not available in strict mode.
I am looking for a method that is not deprecated and works in strict mode.

Try this...

console.log(myFunction.name);

Be aware that this is not supported by IE yet as mentioned here
