An alternative way is to convert the entire thing to a string, replace \n and spaces with blanks, and convert it back to a dict.

window.onscroll = ... is an assignment, so when you copy the same statement you're actually reassigning the window.onscroll listener, that's why only the latest one runs. Instead, you need to assign it once and do all the duplicated stuff inside:

There's a limit when using code generators : they don't know the intention behind the json payload and are unable to make the right decisions when facing complex structures.

In other owrds, don't use them !

The equivalent of a Dictionnary in Dart is a Map. In your case, probably something like a Map with:

That would be: find_by_css_selector('td:nth-child(5n+2)')

You are trying to justify the text by inserting spaces between words.

HTML is a language that specifies the structure of the document, not its formatting. By design, any program that renders HTML replaces a sequence of two or more white space characters (spaces, new lines, tabs) with a single space.

First of all, take a look at the source of your HTML document as it is received by the browser (use Ctrl-U or the Developer Tools command from the menu). This way you can check if your algorithm produces the outcome you expect.

In order to force the browser render the whitespaces as you want, a simple solution is to use non-breaking spaces instead. In HTML, a non-breaking space is encoded as &npsp;.

However, the non-breaking spaces, as their name says, do not allow the browser to break the line at that point (if needed).

Apart from your code being a programming exercise for the justification algorithm, in HTML (+CSS) the standard way to justify a text is to use the text-align: justify; CSS property on the paragraph:
