QUESTION
I just started learning Javascript this week to write a wordgame to help my kid. The idea is that it should show and play a random
word from a dictionary
, she writes it the entry
is checked and random
gets deleted from the dictionary
. The game continues until the dictionary length===0
, and the wrong words are summarised if there are any. Somehow, the program is unpredictable, it literally works 1 in 7 times, and I can't understand why. Giving the following error:
Uncaught (in promise) TypeError: Cannot read property 'word' of undefined
I do think it has something the do with the way I delete random
, or check if the dictonary
is empty. Underneath the code is pasted links to screenshots of the console.log; 1 is the result of the program completely finishing, the other of one that doesn't. The interesting thing is that the error also is unpredictable, sometimes after just 1 word, sometimes 2. The only thing I do is refresh the page and the program behaves differently. I also tried running it on different browsers.
Being a total noob, I was quite surprised that I get different results while trying to do the same thing. It was quite frustrating to find out what was happening :-)

Answered 2021-May-14 at 19:21I just got the issue in your code, it's a bit conceptual thing and nothing much.
See what's going wrong in this screenshot of console
You can see there the length of the dictionary(array) is still the same after deleting the word(object).
Because you have used: delete
keyword which deletes an item and replaces it with empty
and size of the array remains the same.
Hence the new dictionary after deleting the first word became: [empty, {...}, {...}]
Now whenever you will try to get dictionary[0].word
gives you an error: Cannot read property of undefine, because it's empty
Instead of using delete
keyword you can simply use dictionary.splice(random, 1)
QUESTION
I have the code below.
When I have main Run() function run the ResetTrackingTable() function. The ResetTrackingTable() calls 0 for my_n_rows and my_n_cols instead of accessing the existing numbers stored in the private member data.
Why is that? It seems like it's making a new instance of the function...

QUESTION
I cannot use npm to do anything on my Windows 10 machine. I always get: npm ERR! Cannot read property 'resolve' of undefined.
I am using VSCode if that matters.
npm install npm -g
gives me the same message as does "npm i". I have uninstalled Node and reinstalled it twice and it doesn't help. I removed the node-modules directory in my only development directory. I have no other ideas. Please help
This is what the now complete log looks like:
...ANSWER
Answered 2019-Jun-23 at 03:12We do not have much information to work with (as the console output given by Node isn't very useful in this case), but it looks like NPM/Node messed something up while installing.
You stated that you've already tried to re-install Node. You should definitely also re-install NPM (This is a great tutorial to remove both completely: https://stackoverflow.com/a/20711410/10588376).
If you just forgot to mention that you also re-installed NPM and you already did it, I would recommend downgrading Node. You are running v12.4.0 which is the latest (not so stable) version of Node. You could download Node v10.16.0 (https://nodejs.org/en/), which is the LTS (Long Term Support) version of Node (LTS is the recommended version by Node).
As it seems downgrading solved the problem here: https://stackoverflow.com/a/56512076/10588376 (this is for Linux tho, but it could be worth a try on windows too)
QUESTION
I want the output of each of the 5 System.out.Print's to be stored in the sentence(x) variables. Additionally I want to take the last word of each sentence (excluding the punctuation) and set those into their respective variables.
...ANSWER
Answered 2019-Sep-11 at 20:49Not really sure the question, but instead of printing the sentence straight away store it as a variable then just print the variable. Then you are free to use the variables after.Think that might answer your question.
QUESTION
I am trying to compare the letters from the user and a phrase. I want it to walk down each letter. I have "if ((userGuessLength / phraseLength * 100.0) > 75.0)
" as a place holder to just compare string lengths but need it to compare each letter in the string.
how would I modify it to do so?
Example:
Somewhere over the rainbow. - actual phrase
Somewhere over the xxxxxxx. - user guess
19 character are correct (including spaces) 26 characters is the actual phrase length
(19/26) * 100 = 73
percent (they missed)
This is my whole program:

refers to the class itself in a class method or to the current object in an instance method. In your case it refers to WordGame
, the object's class.
If you really want it to refer to 30
into the factors
method you have to define it as an instance method, because called on an object (30
), not a class (Integer
), opening the Integer
