Carl> Python is not a good fit for the browser, in part, because of the syntax.<br>
Carl> JavaScript has issues, but its syntax is better suited to creating GUIs in<br>
Carl> the browser.<br>
<br>
Just so?<br>
<br>
Carl> For example, in browsers everything revolves around a single<br>
Carl> threaded event loop, so you have a lot of callbacks and event<br>
Carl> handlers,<br>
<br>
You can write applications full of callbacks using libraries like<br>
Twisted or even asyncio and you can build entire applications involving<br>
ajax and such without callbacks as JS got async/await too in ES8<br>
<br>
event handlers are written more or less the same in Pyhton or<br>
Javascript<br>
<br>
Carl> which makes function expressions really useful, but Python doesn't have<br>
Carl> expressions that contain blocks, because of significant<br>
Carl> indentation.<br>
<br>
yes, i agree that the difference between lambda an anonymous function is<br>
very significant on the way you may think to write your code.<br>
<br>
Carl> As a result, ordinary JS, like this...<br>
<br>
Carl> $(function(){ $("spam").click(function(){ alert("spam clicked") }) });<br>
<br>
I don't think you mean this is real JS application code :-)<br>
<br>
Carl> ...ends up looking like this...<br>
<br>
Carl> def on_ready():<br>
Carl> def click_handler(): alert("spam clicked")<br>
Carl> jQuery("spam").click(click_<wbr>handler)<br>
Carl> jQuery(on_ready)<br>
<br>
or just<br>
<br>
jQuery(lambda: jQuery("spam").click(lambda: alert("spam clicked")))<br>
<br>
<br>
Carl> JS semantics means JS libraries, which have APIs that assume JS syntax.<br>
Carl> Python library developers make heavy use of language specific features to<br>
Carl> define elegant, Pythonic APIs, which is a big part of what makes the<br>
Carl> language so nice to use.<br>
<br>
language specific features... like?<br>
