underscore.js: _.sum(_.map() ......) compared to: Parallel.sum(parallel.map(......) Where_ is some kind of object proving map and friends Then you could pass around special versions of map etc, like a version specially good for small parallel arrays, one for latency devices (cpus) , one for throughput devices (gpu) or a version with extra debugging Is that far from the spirit of JavaScript? -----Original Message----- From: Brendan Eich [mailto:[email protected]] Sent: Thursday, April 04, 2013 4:34 PM To: Hudson, Rick Cc: Norm Rubin; [email protected] Subject: Re: parallel map and dot product Hudson, Rick wrote: > > In this case it is the same as with a normal array. > > function dotProduct(v1, v2) { > > return v1.map(function (e, i) {return e*v2[i];}).reduce(function (a, > b) {return a+b;}); > > } > So much nicer with ES6 arrow functions (now in SpiderMonkey): function dotProduct(v1, v2) { return v1.map((e, i) => e * v2[i]).reduce((a, b) => a + b); } /be ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
