readability

问题 Context I'm learning how to code in javascript consistently, readably and maintainably. I found nothing about the order of declaration of variables and functions. Example: var example = { A: function() { var a, b, c; }, B: function() { var a, b, c; }, C: function() { var a, b, c; } } Questions Alphabetically is the best one ? Is that the order can improve the speed of code execution ? 回答1: I use jslint to check the code quality. It can be integrated with Visual Studio and a lot of other stuff

问题 I have a code that checks the st_mode of a file: self.assertEqual(16877, os.stat(my_directory).st_mode) Only old school unix experts are able to decipher the integer value 16877 fluently. Is there more readable way to check for exactly this value? 回答1: If I may extend the question a bit and understand it as “Is there more readable way to check file modes?”, then I'll suggest adding a custom assertion. The target: self.assertFileMode(my_directory, user="rwx", group="rx", others="rx") How to do

问题 map and filter are often interchangeable with list comprehensions, but reduce is not so easily swapped out as map and filter (and besides, in some cases I still prefer the functional syntax anyway). When you need to operate on the arguments themselves, though, I find myself going through syntactical gymnastics and eventually have to write entire functions to maintain readability. I'll use map to keep the illustration unit-test simple, but please keep in mind that real-life use-cases might be
