== Why is this an issue?
|
|
|
|
There are several reasons for a function not to have a function body:
|
|
|
|
* It is an unintentional omission, and should be fixed to prevent an unexpected behavior in production.
|
|
* It is not yet, or never will be, supported. In this case an exception should be thrown in languages where that mechanism is available.
|
|
* The method is an intentionally-blank override. In this case a nested comment should explain the reason for the blank override.
|
|
|
|
=== Noncompliant code example
|
|
|
|
[source,javascript]
|
|
----
|
|
function foo() {
|
|
}
|
|
|
|
var foo = () => {};
|
|
----
|
|
|
|
=== Compliant solution
|
|
|
|
[source,javascript]
|
|
----
|
|
function foo() {
|
|
// This is intentional
|
|
}
|
|
|
|
var foo = () => {
|
|
do_something();
|
|
};
|
|
----
|
|
|
|
=== Exceptions
|
|
|
|
* This rule does not apply to function expressions and arrow functions as they can denote default values.
|
|
|
|
[source,javascript]
|
|
----
|
|
static defaultProps = {
|
|
listStyle: () => {}
|
|
};
|
|
----
|
|
|
|
* The rule allows for empty functions with a name starting with the prefix ``++on++`` like ``++onClick++``.

[source,javascript]

|
|
function onClick() {
|
|
}
