Semicolons in QML

[Circuits]

Hey guys, just a general question here about the use of semicolons. Now, from what I understand in JS the semicolon is optional save for a few special cases. Is the same true for QML? For instance, take the following code snip:

  Component.onCompleted:
  {
    state = "selection";
  }

this seems to work exactly the same as:

  Component.onCompleted: state = "selection"

is there a valid argument for the first case over the second in QML?

Yes

For instance, take the following code snip:
Component.onCompleted:
{
state = "selection";
}

this seems to work exactly the same as:
Component.onCompleted: state = "selection"

It is exactly the same.

No, only developer preferences.

With semi-colons you can add more commands on one line.
Brackets are required when using multiple commands for a connection on a signal like Component.onCompleted. For single commands they are optional.

Note: The code to the right-hand-side of : is a JavaScript statement. So, you follow the JavaScript rules of braces and semicolons.

The following snippets are all exactly the same. Like @KroMignon said, just choose the one you prefer.

// Style 1
Component.onCompleted:
{
    state = "selection";
}

// Style 2
Component.onCompleted:
{
    state = "selection"
}

// Style 3
Component.onCompleted: { state = "selection"; }

// Style 4
Component.onCompleted: { state = "selection" }

// Style 5
Component.onCompleted: state = "selection";

// Style 6
Component.onCompleted: state = "selection"
