== Why is this an issue? In JavaScript, the semicolon (``++;++``) is optional as a statement separator, but omitting semicolons can be confusing, and lead to unexpected results because a semicolon is implicitly inserted at the end of each line. === Noncompliant code example [source,javascript] ---- function fun() { return // Noncompliant. ';' implicitly inserted at end of line 5 // Noncompliant. ';' implicitly inserted at end of line } print(fun()); // prints "undefined", not "5" ---- include::../compliant.adoc[] ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) include::../message.adoc[] ''' == Comments And Links (visible only on this page) include::../comments-and-links.adoc[] endif::env-github,rspecator-view[]
