Editing Ternary conditional operator (section)

===JavaScript===
The conditional operator in [[JavaScript]] is similar to that of [[C++]] and [[Java (programming language)|Java]], except for the fact the middle expression cannot be a comma expression. Also, as in C++, but unlike in [[C (programming language)|C]] or [[Perl]], it will not bind tighter than an assignment to its right—{{code|1=q ? a : b = c}} is equivalent to {{code|1=q ? a : (b = c)}} instead of {{code|1=(q ? a : b) = c}}.<ref>{{cite web|title=ECMA-262 Edition 5.1|url=http://www.ecma-international.org/ecma-262/5.1/#sec-11.12|work=Ecma Language Specification|publisher=Ecma International|access-date=7 September 2013}}</ref>

<syntaxhighlight lang="javascript">
var timeout = settings === null ? 1000 : settings.timeout;
</syntaxhighlight>

Just like C# and Java, the expression will only be evaluated if, and only if, the expression is the matching one for the condition given; the other expression will not be evaluated.
