Re: [nodejs] Re: Simple LightWeight OOP. 100% compatibility with JavaScript. Feedback please!

I have yet to hear a particularly convincing argument for this type of OOP in javascript. As Raynos and Isaac explained, the idiomatic js style way without some additional special wrapper or helper is trivial to do. "I like it more" is a fine reason to do it yourself. I think it's a waste of t

Re: [nodejs] ReadableStream from Buffer

There's actually no benefit to breaking up a *big* Buffer into smaller chunks for the purposes of streaming. Once that big buffer is in memory, you're better off just calling .write(buf) on the writable stream and writing the entire Buffer at once; libuv/the kernel will take care of flushing the bu

[nodejs] ReadableStream from Buffer

Hello, Is there a module that creates a ReadableStream given a Buffer, or something like if I write to the stream, it emits the 'data' event every time someone writes to it. I found 2 modules, both of which seem unrelated: https://github.com/dodo/node-bufferstream https://github.com/bnoordhuis

I'm certainly no expert, but I expect the design choice was made to do it that way to make the C/C++ asynchronous calls within the node core to be simpler and easier. At present, to jump back into the callback the C++ side just needs a single function reference. If a list of arbitrary arguments are

If you don't want help and just want a straight answer as to why, the answer is "because". If you don't like the syntax use promises or some compile to JS language to clean it up. But `.bind()` is the way to do this, and it isn't ugly it is just JavaScript. Don't use JavaScript if you don't like J
