=== Noncompliant code example

|
|
[source,javascript]

----
|
|
var a = NaN;
|
|
|
|
if (a === NaN) { // Noncompliant; always false
|
|
console.log("a is not a number"); // this is dead code
|
|
}
|
|
if (a !== NaN) { // Noncompliant; always true
|
|
console.log("a is not NaN"); // this statement is not necessarily true
|
