As far as I know, there are no static compilers for JavaScript. It is certainly theoretically possible; however, a static compilation of JavaScript would need a very heavyweight runtime to support all of its features (such as dynamic typing and eval). As a small aside, when presented with the need to statically compile Python (another …
This might be caused by a cyclic dependencies (i.e. moduleA imports module B and vice versa at the same time). Take a deeper look at your code.
Is this ‘a thing’? Yes. It comes up every now and then, e.g. here. They’re known as IIAFEs 🙂 If you want to put focus on the arrow, you could also call them IIAAFs. Are there pitfalls here I should be aware of? Whenever you call a promise-returning function and don’t return the result to …
There is no difference if this is identity function that just returns an argument and used without type restrictions: const foo: any = fn([‘whatever’]); And there is a difference for typed code: const foo: string = fn(‘ok’); const bar: string = fn([{ not: ‘ok’ }]); Also, the usage of generic type provides semantics. This signature …
Perhaps this will help someone. The solution, for me, was to make sure angular-mocks.js was loaded before my tests. If you’re not sure, you control the order in karma.conf.js under the following section: // list of files / patterns to load in the browser files: [ // include files / patterns here Next, to get …
WebSockets are the best solution for realtime multiplayer games running in a web browser. As pointed out in the comments there is an initial handshake where the HTTP connection is upgraded but once the connection is established WebSockets offer the lowest latency connection mechanism for bi-directional communication between a server and a client. I’d recommend …
Before answering your question directly, it’s worth saying as a starting point: if all you need to do is pull content from static HTML pages, you should probably use a HTTP library (like Requests or the built-in urllib.request) with lxml or BeautifulSoup, not Selenium (although Selenium will probably be adequate too). The advantages of not …
WebAssembly doesn’t natively support a string type, it rather supports i32 / i64 / f32 / f64 value types as well as i8 / i16 for storage. You can interact with a WebAssembly instance using: exports, where from JavaScript you call into WebAssembly, and WebAssembly returns a single value type. imports where WebAssembly calls into …
It seems that your code properly computes the center of the rect and places the text at that point, except that the text is left aligned. If so, you just need to change the text-anchor property to center the text. That would be: textElements.style(“text-anchor”, “middle”)
Yes, they absolutely are different. for await is supposed to be used with asynchronous iterators, not with arrays of pre-existing promises. Just to make clear, for await (const res of items.map(e => somethingAsync(e))) … works the same as const promises = items.map(e => somethingAsync(e)); for await (const res of promises) … or const promises = …
