in your code the snippet Object.keys(data).map(.....) converts it to array. Now when you put this array in string literal JavaScript will try to convert it to a string so it will call .toString() on it which joins all the elements of array using , by default.

instead do this Object.keys(data).map(....).join("") this will join array with empty string

Some recursion should work here:

If your base type is an integer type, the subtype is an integer type. You can't make it an enumeration type.

You can declare constants for your Donuts if you want, then you can refer to them by name. You can instead give the other values names and then have Bakers_Dozen be an enumeration type. If arithmetic operations do semantically not make sense on values of your type, it shouldn't be an integer type anyway.

Try:

This section discusses the specific statements from your sample functions.
See the bottom section for background information.

• $n = 1 and $n++ are assignments and therefore do not produce output.
• $n is an expression whose value is output
• $null - ditto, but even though it is output, it doesn't display by default
• ($n++) - due to enclosure in (...) - turns the assignment into an expression and therefore does output the assigned value (too).
  • However, because you've used the post-increment form of the assignment, it is the old value that is output, not the now incremented value; to increment first (pre-increment) and then output, use (++$n)
• [System.Console]::WriteLine("Hello") prints directly to the console, which bypasses PowerShell's system of output streams.
  • This means you cannot capture or redirect such output from inside PowerShell (see the next section).

^{Tip of the hat to iRon for his help.}

PowerShell, following the model of traditional shells, is organized around streams - see the conceptual about_Redirection help topic for an overview of all 6 streams that PowerShell supports.^[1]

That is, any statement - and therefore potentially multiple ones - in a script or function can write to any of the output streams.

The primary output stream, meant to convey data, is the success output stream (whose number is 1), and only it is sent through the pipeline by default, and therefore by default only it is captured in a variable, suppressed, or redirected to a file.

There are two ways to write to the success output stream, i.e. to produce data output:

• Explicitly, with a Write-Output call - although that is rarely needed.

• Typically implicitly, by neither capturing, suppressing, nor redirecting output produced by a statement.

  • In other words: Output from any command (e.g., Get-ChildItem *.txt) or expression (e.g, 1 + 2 or (42).ToString('x')) is sent to the success output stream by default.

  • Unlike in traditional programming languages, return is not needed to produce output - in fact, its primary purpose is to exit the enclosing scope independently of any output the scope produces, though as a syntactic convenience you can combine the two aspects:

    • return is in effect the same as the following two statements, the first of which (potentially) produces output, the second of which exits the scope: ; return

  • This implicit output behavior is convenient and and allows for concise, expressive code, but can also be a pitfall: it is easy to accidentally produce output - typically from a .NET method whose return value isn't needed (see this question for an example).

    • iRon's GitHub feature request #15781 discusses one potential way to remedy this problem: introduction of an opt-in strict mode that only permits using explicit output statements (Write-Output, return) in order to produce output.

    • This answer shows troubleshooting techniques you can use with the currently available features.

As for assignments - e.g. $n = 1; $n += 1; ++$n; $n--:

• By default they do not produce output.
  • A hybrid case is the chaining form of a multi-assignment, e.g. $a = $b = 1, which assigns 1 to both variables: statement-internally the assignment value is passed through, but the statement as a whole has no output.
• However, as an opt-in you can make them pass the value(s) being assigned through via (...), the grouping operator; e.g. ($n = 1) both assigns 1 to variable $n and outputs 1, which allows it to participate in larger expressions, such as ($n = 1) -gt 0
  • Note that the related $(...) (subexpression operator) and @(...) (array-subexpression operator) do not have that effect - they wrap one or more entire statement(s), without affecting the enclosed statements' intrinsic output behavior; e.g. $($n = 1) does not produce output, because $n = 1 by itself doesn't produce output; however, $(($n = 1)) does, because ($n = 1) by itself does.

As for output enumeration behavior:

• By default, PowerShell enumerates collections that are being output, in the spirit of streaming output: That is, it sends a collection's elements to the pipeline, one by one.

• In the rare event that you do need to output a collection as a whole - which in general should be avoided, so as not to confound other commands participating in a pipeline, which usually do expect object-by-object input - you have two options:

  • , $collection (sic; uses an aux. one-element wrapper array)
  • More explicitly, but less efficiently: Write-Output -NoEnumerate $collection
  • See this answer for more information.

As for outputting $null:

• $null is output to the pipeline, but by default doesn't show.

  • $null by itself produces no visible output,

  • but the following returns $true, demonstrating that the value was sent:

What the docs say beautifulsoup documentation:

AttributeError: 'NoneType' object has no attribute 'foo' - This usually happens because you called find() and then tried to access the .foo attribute of the result. But in your case, find() didn’t find anything, so it returned None, instead of returning a tag or a string. You need to figure out why your find() call isn’t returning anything.

You can use the group_concat aggregate function:

You have too much code too see where the problem is happening. Is this the filter you are looking for?

You can make use of String#includes() and String#charAt() to check each character in the userGuess against the pickedWord.

The snippet below uses the results to wrap each character in a span of the appropriate color. You can refactor the HTML generated as needed.
