== Why is this an issue?
|
|
|
|
include::../description.adoc[]
|
|
|
|
Code like
|
|
|
|
[source,javascript]
|
|
----
|
|
if (x != undefined) {
|
|
if (y === 2) {
|
|
// ...
|
|
}
|
|
}
|
|
----
|
|
|
|
Will be more readable as
|
|
|
|
[source,javascript]
|
|
----
|
|
if (x != undefined && y === 2) {
|
|
// ...
|
|
}
|
|

|
|
|
|
|
|
== How to fix it
|
|
|
|
If merging the conditions seems to result in a more complex code, extracting the condition or part of it in a named function or variable is a better approach to fix readability.

=== Code examples

|
|
|
==== Noncompliant code example
|
|
|
|
[source,javascript]
|
|
----
|
|
if (file != undefined) {
|
|
if (file.isFile() || file.isDirectory()) { // Noncompliant
|
|
/* ... */
|
|
}
|
|
}
|
|
----
|
|
|
|
==== Compliant solution
|
|
|
|
[source,javascript]
|
|
----
|
|
function isFileOrDirectory(File file) {
|
|
return file.isFile() || file.isDirectory();
|
|
}
|
|
|
|
/* ... */
|
|
|
|
if (file. != undefined && isFileOrDirectory(file)) { // Compliant
|
|
/* ... */
|
|
}
