Self referential anonymous function

[anacrolix]

This kind of code seems quite common:

console.log('meh');
(function a() {
    console.log('hiya');
}());

But standard formats it like so:

console.log('meh');(function a () {
  console.log('hiya')
}())

It's rather:

console.log('meh')
;(function a () {
  console.log('hiya')
}())

Also, you'll find a couple of reasons not to use this sorrily common pattern.

Feel free to enlighten me.

Self-calling functions need to be prepended with a ; to prevent it from being interpreted as a call to the returned value from the previous line (e.g. console.log()()).

What I meant was that you should avoid using IIFEs if you can :)

Pretty sure that @anacrolix is referring to standard-format. When I run his code through it, it joins the two first lines into one: console.log('meh');(function a () {.
