How to fix   Complexity   

Complexity

Complex classes like javascripts/respond.js often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes.

Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.

You are extending the built-in type Object. This may have unintended consequences on other objects using this built-in type. Consider subclassing instead.

The variable navigator seems to be never declared. If this is a global, consider adding a /** global: navigator */ comment.

This checks looks for references to variables that have not been declared. This is most likey a typographical error or a variable has been renamed.

Complexity Best Practice introduced by
There is no return statement if _2a._2c !== null is false. Are you sure this is correct? If so, consider adding return; explicitly.

This check looks for functions where a return statement is found in some execution paths, but not in all.

Consider this little piece of code

function isBig(a) {
    if (a > 5000) {
        return "yes";
    }
}

console.log(isBig(5001)); //returns yes
console.log(isBig(42)); //returns undefined

The function isBig will only return a specific value when its parameter is bigger than 5000. In any other case, it will implicitly return undefined.

This behaviour may not be what you had intended. In any case, you can add a return undefined to the other execution path to make the return value explicit.

Complexity Best Practice introduced by
There is no return statement if typeof document.document...lement.clientWidth != 0 is false. Are you sure this is correct? If so, consider adding return; explicitly.

This check looks for functions where a return statement is found in some execution paths, but not in all.

Consider this little piece of code

function isBig(a) {
    if (a > 5000) {
        return "yes";
    }
}

console.log(isBig(5001)); //returns yes
console.log(isBig(42)); //returns undefined

The function isBig will only return a specific value when its parameter is bigger than 5000. In any other case, it will implicitly return undefined.

This behaviour may not be what you had intended. In any case, you can add a return undefined to the other execution path to make the return value explicit.

This checks looks for references to variables that have not been declared. This is most likey a typographical error or a variable has been renamed.
