Constructor functions, which create new object instances, must only be called with new
. Non-constructor functions must not. Mixing
these two usages could lead to unexpected results at runtime.
Noncompliant Code Example
function getNum() {
return 5;
}
function Num(numeric, alphabetic) {
this.numeric = numeric;
this.alphabetic = alphabetic;
}
var myFirstNum = getNum();
var my2ndNum = new getNum(); // Noncompliant. An empty object is returned, NOT 5
var myNumObj1 = new Num();
var myNumObj2 = Num(); // Noncompliant. undefined is returned, NOT an object
