What JavaScript minifier do you recommend?
UglifyJS2, used by the jQuery project.
Active
Closure Compiler
UglifyJS2
Deprecated
YUI Compressor
UglifyJS
Google Closure Compiler generally achieves smaller files than YUI Compressor, particularly if you use the advanced mode, which looks worryingly meddlesome to me but has worked well on the one project I've used it on:
Several big projects use UglifyJS, and I've been very impressed with it since switching.
JavaScript Minifier gives a good API you can use programatically:
curl -X POST -s --data-urlencode 'input=$(function() { alert("Hello, World!"); });' http://javascript-minifier.com/raw
Or by uploading a file and redirecting to a new file:
curl -X POST -s --data-urlencode 'input#ready.js' http://javascript-minifier.com/raw > ready.min.js
Hope that helps.
If you are using PHP you might also want to take a look at minify which can minify and combine JavaScript files. The integration is pretty easy and can be done by defined groups of files or an easy query string. Minified files are also cached to reduce the server load and you can add expire headers through minify.
There are several you can use/try:
YUI compressor
jsmin
Microsoft Ajax minifier (has hypercrunching)
Pretty Diff - http://prettydiff.com/?m=minify
Sometimes i use this: http://closure-compiler.appspot.com/home
This tool: jscompressor.com is pretty good.
YUI minifier

I want to pursue towards becoming a FULL stack developer before that I want to get my grip on Angular.
I already know about the differences between AngularJS and Angular, my question is,
Is it necessary to learn AngularJS before learning Angular 4-6?
If not, can I apply for any project/job that has a listing requirement of AngularJS?
Summary: Can I directly learn Angular 4-6 from scratch without AngularJS?
Also, please suggest regarding which version of Angular (2-6) should be choosed to learn from scratch.
no it is not necessary to know AngularJs to lear Angular4-6 but i recommend you to first take a look on typeScript because it is necessary before you get started with Angular4-6 you should start with Angular5 because it is latest and there is not much difference in Angular5 and Angular6 which is better for getting familiar with Angular
You may skip AngularJS, though understanding vanilla, ECMA javascript and typescript is at must before you start to learn any kind of JS framework.
Talking about which version to start learning, I'd rather started upon learning the latest version possible, then invested some time reviewing changelog afterwards.
While you understand that tech, the latest version will become stable and popular.
While they share many concepts, AngularJS and Angular are two completely independent frameworks. There is no need to know one before learning the other.
Angular is very different from AngularJS. Ultimate version of AngularJS has been released so it is in sunset phase of it's life now...
http://www.codelord.net/2018/02/04/angularjs-1-dot-7-the-ultimate-version/
Google say that in October 2017 the number of active Angular (that is,
2+) developers has surpassed that of AngularJS developers, which was
their cue all along to when they can start wrapping up 1.x.
Regarding the job - I think that future of the angularJS projects is migration to Angular/Vue/React so your Angular skills might be relevant. You may apply and let them decide.
I suggest to start learning from the most actual version which is 6 now

So I went through a good tutorial of Angular 1.x.
I visited angular.io to have a look at Angular 2.
All I can see is Typescript, Javascript, and Dart references.
Is what I learnt about Angular pointless now and should I start learning Typescript?
Thanks
TypeScript is only a superset of Javascript. So everything you can do in JS, you can automatically do with TypeScript, too.
With Angular 2 the whole framework changed. Things that partially stayed similar is the template rendering, where only a few keywords changed their name, but the overall concept stayed the same.
The approach for building the app however changed completely.
I'd suggest this article. Be careful though, since a few things stated on that page are already outdated again.
Yes, of course you should start learning Angular2 with Typescript(or any other available platform).
Angular2 framework has been written from the scratch in Typescript.
Believe me by far its one of the best frameworks available nowadays.It provides many features(You'll come to know once you start learning it). Testing components has become so easy.
You can use javascript, dart & typescript with Angular2. I prefer to use Typescript with Angular2. Compare to Javascript, typescript is easy and helpful. There is a separate process which converts your typescript code to javascript code.
while coming from Angular1.x(with JS) background, I understand it is not easy as Angular2.0 is not directly related to Angular1.x.
But soon Angular1.x will be replaced by Angular2.0 and then you will have to learn it so better to start learning now.
Additionally, you can migrate your Angular1.x apps to Angular2.0 with upgrade process
I have so many things to say but I think this much will help to go ahead.

I'd like to learn to create a website with processing on the client side.
Here are my goals:
- The program would look like something like Picasa or Lightroom. It means processing lot of pictures in a row
- I'd like the client to download the "image processor" to avoid uploading plenty of pictures on the server (which is slow and frustrating IMHO).
- I also have in mind to create a mobile version of the website
I don't know a lot about internet programming languages but here are my thoughts at the moment:
Flash: I think it would do, but I don't like it (not portable enough from what I read)
Java: This is the one I am thinking of at the moment. But I don't like the idea of asking users to download a third party if they don't have it.
HTML5 + Javascript: I don't what it means regarding Javascript capabilities. Would it be a pain?
Python, Ruby on Rail, C#: I don't know what it means to use them for web programming. I already used Python put as scripting language.
There are for sure other technologies that I am not aware of. Feel free to propose anything else that is mainstream enough to get good support on the internet :)!
Thank you for your help!
I hope you won't think it is a duplicate. I made some search and found this for ex:
Client-side image processing
=> But they already have their core processing since I have nothing!
Modern web browsers support html5 & javascript out of the box - older ones at least have support for javascript unless support for something truely ancient is desired - so considering the compatibility it should be the best one of these alternatives.
Flash needs a flash-plugin and a Java applet needs a jre-plugin.
Have never seen the 4th choice in client-based web-applications really, so not sure about how that would be done.

I would like to have async loading of angular dependencies in a large application and I'm trying to decide between Browserify or Webpack for this. I know angular 2.0 will support this natively but for now I'm looking for a well supported and popular solution.
Can anyone give advice on which ones works best in an angular team and the most optimal way to structure the project.
At my company, we've switched over from browserify to webpack for a multitude of reasons, lazy loading being one of them.
Putting things in multiple bundles in browserify took some configuration changes as well as special code. Here is a great guide for that http://esa-matti.suuronen.org/blog/2013/04/15/asynchronous-module-loading-with-browserify/
With webpack, adding a new bundle just means an extra entry file line in the configuration's entry file line. Here is a quick guide to that: https://github.com/petehunt/webpack-howto#7-multiple-entrypoints. In the case of lazy-loading, you don't even need to change anything in the configuration file, which is awesome - just use the asynchronous require syntax detailed here: https://github.com/petehunt/webpack-howto#9-async-loading
Here is a template for a setup very similar to what we use at https://bench.co in production. https://github.com/jeffling/angular-webpack-example/
Hi you should go with webpack as it supports multiple filetypes (css, js +++), and can separate code in multiple modules.

i want to write a simple web app that can connect to databases and display simple text and images. I know a bit of programming - mainly C. Also i have a very short time frame for learning the language and technologies associated with it. Which language would be good/ also what would be a good starting point
If you know C, PHP should come naturally.
It's also:
Widely deployed
Easy to get started
Built exclusively for the web
Plenty of resources for learning
Have a look at Ruby on Rails, especially the screencast on their homepage, “Creating a weblog in 15 minutes with Rails 2”.
The syntax is different from C but on the other hand there’s practically no learning curve for simple web applications.
You can't get much simpler than PHP. It's got C-type syntax. It's available nearly everywhere.
As an alternative to PHP, try Python with Django. It's very quick to learn, a much nicer language than PHP, and has a good community. The only issue is it's not as widely deployed as PHP. But if you control the server then that shouldn't matter.
PHP syntax is similar to C and it won't take much time to build a simple app.
PHP is one of the easiest language i've known :).
Every time you are talking about a web application you get involved into javascript stuff so I say you give node js a try because it's fast and it has a lot of tools that could be integrated into your application with a few commands
