== Why is this an issue?

An array declared with missing ("sparse") elements is likely to be an error: an extra comma was inserted or perhaps the developer meant to insert the missing value and forgot.


=== Noncompliant code example

[source,javascript]
----
let a = [1, , 3, 6, 9];  // Noncompliant
----


=== Compliant solution

[source,javascript]
----
let a = [1, 3, 6, 9];
