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
function fun() {
return // Noncompliant. ';' implicitly inserted at end of line
5 // Noncompliant. ';' implicitly inserted at end of line
}
print(fun()); // prints "undefined", not "5"
Compliant solution
function fun() {
return 5;
}
print(fun());
