  While named function expressions might be useful for debugging purposes, some browsers do not support them correctly (for example Internet Explorer 8).


Noncompliant Code Example
f = function fun(){}; // Non-Compliant;  named function expression


Compliant Solution
fun = function(){}; // Compliant; function expression


Exceptions
ECMAScript 6 generator functions are excluded from this rule.
function* f() {} // Compliant; generator function.
