The ``++new++`` keyword should only be used with objects that define a constructor function. Use it with anything else, and you'll get a ``++TypeError++`` because there won't be a constructor function for the ``++new++`` keyword to invoke. == Noncompliant Code Example ---- function MyClass() { this.foo = 'bar'; } var someClass = 1; var obj1 = new someClass; // Noncompliant; var obj2 = new MyClass(); // Noncompliant if considerJSDoc parameter set to true. Compliant when considerJSDoc=false ---- == Compliant Solution ---- /** * @constructor */ function MyClass() { this.foo = 'bar'; } var someClass = function(){ this.prop = 1; } var obj1 = new someClass; // Compliant var obj2 = new MyClass(); // Compliant regardless of considerJSDoc value ----
