Curly braces around statements make for more readable code and help prevent bugs when you add further statements.
                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Consider adding curly braces around all statements when they are executed conditionally.
This is optional if there is only one statement, but leaving them out can lead to unexpected
behaviour if another statement is added later.


Consider:


if (a > 0)
    b = 42;





If you or someone else later decides to put another statement in, only the first
statement will be executed.


if (a > 0)
    console.log("a > 0");
    b = 42;





In this case the statement b = 42 will always be executed, while
the logging statement will be executed conditionally.


if (a > 0) {
    console.log("a > 0");
    b = 42;
}





ensures that the proper code will be executed conditionally no matter how
many statements are added or removed.

There is no return statement if ns6 || ie 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.

Consider adding curly braces around all statements when they are executed conditionally.
This is optional if there is only one statement, but leaving them out can lead to unexpected
behaviour if another statement is added later.


Consider:


if (a > 0)
    b = 42;





If you or someone else later decides to put another statement in, only the first
statement will be executed.


if (a > 0)
    console.log("a > 0");
    b = 42;





In this case the statement b = 42 will always be executed, while
the logging statement will be executed conditionally.


if (a > 0) {
    console.log("a > 0");
    b = 42;
}





ensures that the proper code will be executed conditionally no matter how
many statements are added or removed.

Curly braces around statements make for more readable code and help prevent bugs when you add further statements.
                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Consider adding curly braces around all statements when they are executed conditionally.
This is optional if there is only one statement, but leaving them out can lead to unexpected
behaviour if another statement is added later.


Consider:


if (a > 0)
    b = 42;





If you or someone else later decides to put another statement in, only the first
statement will be executed.


if (a > 0)
    console.log("a > 0");
    b = 42;





In this case the statement b = 42 will always be executed, while
the logging statement will be executed conditionally.


if (a > 0) {
    console.log("a > 0");
    b = 42;
}





ensures that the proper code will be executed conditionally no matter how
many statements are added or removed.

Curly braces around statements make for more readable code and help prevent bugs when you add further statements.
                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Consider adding curly braces around all statements when they are executed conditionally.
This is optional if there is only one statement, but leaving them out can lead to unexpected
behaviour if another statement is added later.


Consider:


if (a > 0)
    b = 42;





If you or someone else later decides to put another statement in, only the first
statement will be executed.


if (a > 0)
    console.log("a > 0");
    b = 42;





In this case the statement b = 42 will always be executed, while
the logging statement will be executed conditionally.


if (a > 0) {
    console.log("a > 0");
    b = 42;
}





ensures that the proper code will be executed conditionally no matter how
many statements are added or removed.
