There was a problem hiding this comment.
str (the parameter) works like a local variable.
Redeclaring str using var has no effect on str (Note: Redeclaring str using let or const is prohibited)
So
var str = `${str[0].toUpperCase()}${str.slice(1)}`;
is identical to
str = `${str[0].toUpperCase()}${str.slice(1)}`;
In general, avoid using var because it can make our code behave in unexpected ways (if not used properly); let and const are safer.

The function is expected to return a string in pound format. Outputting the string to console is not the same as returning the string.

To more precisely express a value is a string, we can enclose the value by a pair of double quotes. For example, "00".
