Biplab Malakar Thanks. So you can only use it if you incorporate a build process. Okay. -Mike

Nice article! For this backend developer who does not do much Javascript in the browser, how viable is using ES6 on the open web today? What percent of browser can use it? And what happens when a user's browser does not support ES6; is there a polyfill? Is polyfill even possible? Thanks in advance.

Hugo Delgadinho Thanks. Good article!

That post is interesting, and mostly good. But if you read the comments many people who replied point out that the author was overzealous with their dismissal of recursion. Ironically, one of the authors other claims is to not use the heap yes an iterative algorithm is more likely to use the heap than a recursive one because you have to keep track of that state somewhere. So, use recursion when the data structure is recursive, such as an HTML DOM or a directory structure or object graph. If you are worried about infinite recursion pass in a depth variable and increment it each level, test for a max number of levels and fail gracefully if it uses too many levels. P.S. Who was it that specifically made you fear recursion? Maybe we need to give that person some mob justice? #onlykidding

No love?

Would love to learn how to use runc .

Thanks for your reply. When I type flutter channel master I get what appears to be a git pull from https://github.com/flutter/flutter and then these are the last lines in the output: git: Please commit your changes or stash them before you switch branches. git: Aborting Switching channels failed with error code 1. Is there some directory that we must be in that your article does not mention? I am new to Flutter so I don't know anything about its directory layout or any other aspects of Flutter, but I am very interested in something to build cross-platform desktop apps besides Electron.

When I type flutter devices I get No devices detected . I have Intellij IDEA Ultimate install but not VC Code. Is there something more that needs to be done that you maybe overlooked because your system already had it?

Sky I work in both PHP and Go concurrently; 12 years and 1 year, respectively. And I really, really, really wish the PHP team would listen to the language criticisms of people who program in Go and related languages. Things like being able to recover from 100% of errors, making ArrayObject() 100% compatible with PHP arrays and more. We could do so much with PHP if they would just throw us a few crumbs... I could go on. And on. But out of courtesy to Alejandro I won't. :-)

Thanks! What other languages do you program in?
