Empty statements represented by a semicolon ; are statements that do not perform any operation. They are often the result of a typo or
a misunderstanding of the language syntax. It is a good practice to remove empty statements since they don’t add value and lead to confusion and
errors.
Noncompliant code example
function doSomething():void {
; // Noncompliant - was used as a kind of TODO marker
}
function doSomethingElse():void {
trace("Hello, world!");; // Noncompliant - double ;
...
for (var i:int = 0; i < 3; trace(i), i++); // Noncompliant - Rarely, they are used on purpose as the body of a loop. It is a bad practice to have side-effects outside of the loop body
...
}
Compliant solution
function doSomething():void {}
function doSomethingElse():void {
trace("Hello, world!");
...
for (var i:int = 0; i < 3; i++){
trace(i);
}
...
}
