In the scenario where the else statement is blank, is it's inclusion necessary? IE:
if (condition) {
function
}
else {}
or
if (condition) {
function
}

7No, you don't *need* an `else` statement – George Jan 10 '14 at 12:05

1Empty `else` block is completely unnecessary. – pawel Jan 10 '14 at 12:06

Why don't you try it yourself? This takes less than 10 secs. – user1983983 Jan 10 '14 at 12:08

You can even write it as `if (condition) function` if you so wanted. Curly braces are your friends tho. – Andy Jan 10 '14 at 12:08

Only for the short-hand `?` you need a pendant of else (`:`). – Grim Jan 10 '14 at 12:10

@PeterRader: and not a full shorthand at that, e.g. you can't throw an error directly from one (it's a statement, not a expression). – Qantas 94 Heavy Jan 10 '14 at 12:35

The inclusion of the else statement is not necessary.
if (condition) {
function();
}
is enough.

For single lines in the `if` body, you can even avoid the curly brackets. – Cedric Reichenbach Jan 10 '14 at 12:28
