SPI usage

[espruino-discuss]

right now i need to write the following to create a working SPI object

var spi = new SPI(); // or SPI1, 2,3
spi.setup(options);

i would like to be able to use

var spi = new SPI().setup(options);
// or even better
var spi = new SPI(options);

maybe there is some downside to my approach, i would like to know it :-)

Well, you can't do that right now, but either of those is possible with some changes to Espruino.

... although playing devil's advocate here, it's only really saving a few characters - what's it really gaining you? Or am I missing something...

just style (maybe some API uniformity), although some parts of espruino API work this way (constructor with options or setup which returns the object), e.g.
