How to fix   Complexity   

Complexity

Complex classes like prettify.js ➔ k 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.

Comprehensibility introduced by
else is not necessary here since all if branches return, consider removing it to reduce nesting and make code more readable.

Coding Style introduced by
Consider using undefined instead of void(0). It is equivalent and more straightforward to read.

Unused Code Comprehensibility introduced by
The assignment of undefined is not necessary as V is implicitly marked as undefined by the declaration.

The variable am already seems to be declared on line 2. Consider using another variable name or omitting the var keyword.

This check looks for variables that are declared in multiple lines. There may be several reasons for this.

In the simplest case the variable name was reused by mistake. This may lead to very hard to locate bugs.

If you want to reuse a variable for another purpose, consider declaring it at or near the top of your function and just assigning to it subsequently so it is always declared.

The variable X is changed as part of the for loop for example by X++ on line 2. Only the value of the last iteration will be visible in this function if it is called after the loop.

You seem to be aliasing the built-in name Date as W. This makes your code very difficult to follow, consider using the built-in name directly.

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