You're welcome. And, I think you'll learn to like it once you get past the WTFs with the learning curve that is. 
Since it's always fun to see demos, try doing this without JavaScript. It would be impossible...

Even if you use WebGL, canvas, et al they are controlled by JavaScript. So learning it is essential for client interactivity.

It can be a good tool - especially if you are used to typed languages... But, at the end of the day it translated to JS and that what runs on the clients machine, so using TS does not relieve you from learning JS...

Indeed it doesn't (nor was I suggesting that it does). What you do get from this, is well written examples of the language when the code has been transpiled so it becomes easier for you to grok how certain things should be structured.

I am not a fan of javascript, but it has become a serious and mighty programming language over the years.
It is depending on the developer and it skill to use it in strict mode.

When it comes to Javascript, I started by crying. That turned into screaming. Now I just quietly whimper.

I do not understand why so many people hate and whine about JavaScript. I've been using it for years and once you understand how web programming works, JS is easy. Then I found jQuery which was really confusing at first until I got the hang of it and now it is awesome.
It is not that hard nor that bad. w3schools has some good information. I'd suggest doing a project and then just google how to do what it is you need to do. Learn by doing, that's what works best for me.

There are only 10 types of people in the world, those who understand binary and those who don't.

Hi,
I would highly recommend these[^] videos by Douglas Crockford.
I have been using JavaScript off-and-on since the late nineties but there are a lot of caveats. An "interesting" language and things have been changing quite a bit with module loading and the like.
Once you get the hang of it you'll want to probably get going on one of the MV* frameworks. I have used Ember.js (3 years) before but currently I prefer CanJS[^] as I like the design and the fact that it is more library-focused and not so much a framework.
Regards,
Eben

Look at the free jQuery book here.
https://www.syncfusion.com/resources/techportal/ebooks
This will give you a good idea of basic use. After the book, the jQuery online documentation will help you refine the basics for a particular usage.
You really also need some basics on web page layout and CSS to go along with jQuery.

JavaScript is a dynamically typed language based around event driven programming. Everything is based around the idea of callbacks. If you are writing NodeJS or only targeting modern browsers then you get a 'Promise' - which is an object that lets you call a 'then' member to give it a callback. It's all centred around an event loop. (Bottom line is: understand what a callback is)
Do yourself a favour, and unless you're given no other choice - avoid NodeJS like the plague. Every other server side technology ranging from Python Applications written in WSGI, ASP.Net and JSP, through to FCGI written in C (no that last one isn't an exaggeration, the logic is easier to follow) are easier to work with and understand.
I would say the place to start with client-side JavaScript is in understanding the DOM, and how to program it. I actually have a hunch that custom elements would be a good place to start if you're already knowledgeable in how to program. To change the appearance of anything in the browser though you probably need to also understand CSS - which in my opinion is actually the harder challenge as it's a declarative language that doesn't agree with most people.
If you can master both you can move onto manipulating the CSSOM with JavaScript.

Thank you. Understanding DOM programming is a good idea. I'll definitely look into that.

Read one of the HTML(5), CCS(3), JavaScript "in 24 hours" books and start with the basics.
Learn them in this order otherwise: HTML; CSS; JavaScript (one builds on the other: content -> presentation -> interaction).
Some of the smartest and best people in the field don't use any "frameworks" (like JQuery).
Decide for yourself, later.

I want to simulate a virtual mouse with cursor,so i can use code to control it to do some automation service software, It doesn't conflict with real mouse. Does everyone know how to do this? thx.

Step 1: see the bold, red text a little above your message.
Step 2: do what it says.

not understand what you say, can you point it in detail?
|

|

Look at the top of this page where it says Welcome to the Lounge
Read the message below it.

What if I want to simulate reading the message, how do I do that?

Also, it'll help to tell us what the use case for this is in better detail. If any of the old timers here get the feeling you're trying to make malware, you're not gonna get much help.

Put your question in the right forum. There is one for hardware, go there.

While the others here have redirected you to ask the question in the right place I will go easy on you and answer your question.
No - not everyone here knows how to do this.
Does that help?

Presumably you already verified that it cannot be run via the command line (no mouse.)
I would guess in general that is not possible. Certainly difficult.
From the debugging point of view you would still want to 'turn on' the real mouse so you could see where the pointer to the application is going. When not doing that then the mouse pointer for the application could not be visible as it would cause confusion.
I know there is automation software that uses the mouse. But it uses the real mouse. If you run it on a client machine you just sit back and watch until it is done.
