                                                                                      I have scripts In my React app that are inserted dynamically later on. The scripts don't load.

                                                                                      In my database there is a field called content, which contains data that includes html and javascript. There are many records and each record can include multiple scripts in the content field. So it's not really an option to statically specify each of the script-urls in my React app. The field for a record could for example look like:

                                                                                      Some text and html

                                                                                      Some text. Etc…

                                                                                      I call on this field in my React app using dangerouslySetInnerHTML:

                                                                                      render() {
                                                                                          return (
                                                                                              
                                                                                                  
                                                                                                      
                                                                                                      ... some other data
                                                                                                  
                                                                                              
                                                                                          );
                                                                                      }
                                                                                      

                                                                                      It correctly loads the data from the database and displays the html from that data. However, the Javascript does not get executed. I think the script doesn't work because it is dynamically inserted later on. How can I make these scripts work/run?

                                                                                      This post suggest a solution for dynamically inserted scripts, but I don't think I can apply this solution because in my case the script/code is inserted from a database (so how to then use nodeScriptReplace on the code...?). Any suggestions how I might make my scripts work?

                                                                                      npm i node-fetch@2.6.1

The jsconfig.json file specifies the root files and the options for the features provided by the JavaScript language service.

                                                                                      Check more details here: https://code.visualstudio.com/docs/languages/jsconfig

                                                                                      I try to fill a text field with Capybara's fill_in method. While debugging I noticed that Capybara has problems especially with the symbols @ and \. Every other character can be written into the text field without any problems.

                                                                                      The code that triggers the error looks like this

                                                                                      In this link you will see how it is solved (in C#) --> Selenium - SendKeys("@") write an "à"

                                                                                      All basic solutions like flutter clean, flutter pub get, pod deintegrate & install, flutter build ios, flutter run but still same issue. only on iOS simulator not deploying.

                                                                                      Any solution for this. Thanks in advance.

                                                                                      I've searched about it on ecmascript standard, and saw this:

                                                                                      The first step is converting the input to `string` if it is not:

                                                                                      19.2.5 parseInt ( string, radix )

                                                                                      The parseInt function is the %parseInt% intrinsic object. When the parseInt function is called, the following steps are taken:

                                                                                      1. Let inputString be ? ToString(string).
                                                                                      2. Let S be ! TrimString(inputString, start).

                                                                                      ...

                                                                                      So, I've checked the values on string-based using String function to see what is the output for each of them:

                                                                                      String(0.5);      // => '0.5'
                                                                                      String(0.05);     // => '0.05'
                                                                                      String(0.005);    // => '0.005'
                                                                                      String(0.0005);   // => '0.0005' 
                                                                                      String(0.00005);  // => '0.00005'
                                                                                      String(0.000005); // => '0.000005'
                                                                                      
                                                                                      String(0.0000005); // => '5e-7'
                                                                                      

                                                                                      So, it means when we use parseInt(0.0000005), it is equal to parseInt('5e-7') and based on the definition:

                                                                                      parseInt may interpret only a leading portion of string as an integer value; it ignores any code units that cannot be interpreted as part of the notation of an integer, and no indication is given that any such code units were ignored.

                                                                                      So the answer will return 5 only because it is the only character which is a number till a noncharacter e, so the rest of it e-7 will be discarded.

The domain and range of indexing is not necessarily the same -- the domain is arrays and objects, but the range is any type of object, since array elements and object properties can hold any type. If you have an array of integers, the domain is Array, while the range is Integer, so it's not possible for there to be an identity. a[x] will always be an integer, which can never be equal to the array itself.

                                                                                      And even if you have an array of arrays, there's no reason to expect any of the elements to be a reference to the array itself. It's possible to create self-referential arrays like this, but most are not. And even if it is, the self-reference could be in any index, so there's no unique identity value.

They mentioned you would need to un-comment a line in app/javascript/application.js, however mine is pretty empty:

The mono project used to have a WASM SDK that you could download from their old Jenkins server, but that is no longer public. Existing docs tend to point toward those builds. The Azure Devops builds do not include this SDK. A few messages I've seen on their Github account indicate that they are now focusing on the .NET 6 for WASM. I do not wish to use the Blazor components. Is there a way in .NET 6 to build a minimally sized WASM binary without the Blazor UI?
