What does this.async() do in JavaScript
(3 answers)
Closed 3 years ago.
This might be a possible duplicate of this question What does this.async() do in JavaScript but that question is under a different circumstance and the accepted answer got negative vote, hence wrong or original question unaddressed. Also the most liked answer did not clarify it, the answerer also said so in his answer.
What is the actual use of this.async(); is JS? Is it part of the core JS language or a conventional function used by libraries? I couldn't find any documentation on this.
The this.async() is not standard (core) JS function
this.async();
If anybody else is wondering about this. I just found this link which kind of sums it up and details the use case.
https://github.com/sboudrias/run-async#readme
And Grunt also use this same technique to know that an async task has finished.

Is it possible to sandbox JavaScript running in the browser?

I'm aware similar questions have been asked before, but my use-case is a little different.
I'd like to create an educational app similar to LeetCode, CodeWars, etc. where users can type in their own functions to solve algorithms.
Right now, I'm focusing on JavaScript, so the code could be evaluated on client-side.
I want to know, what considerations should I take into account to use eval() and new Function() safely?
Or is there a better alternative?
Luckily you're not alone, and someone invented the wheel before you. You can check out NeilFraser/JS-Interpreter or sandbox.
There may be even better documented/implemented solutions that I'm not aware of, but it's a good start.

I develop a small website now some of my friends asking to give us the code.so i want now to do a trick in my code that no one can copy or modify my code.if any one know's please post.
Copy: Forget it. If you give the code to someone, he can just copy and re-use it. Consider using an appropriate license for your code to make shure the receiver knows what he is allowed to do with your code
Changes: Use a version control system. As a developer you must learn to use at least one. Do it now. I recommend git, but there are plenty of VCS`ses available (svn,bazaar,cvs...)

I'll keep my question short. I've read this question about a delay function.
How to wait 5 seconds with jQuery?
and it struck me that people wanted to know about alternative ways to achieve this using JQuery.
In my understanding JQuery is nothing but a JS library. In many cases to introduce new functionality.
Now why would someone use JQuery if an original JS function is available and not even too complex?
Bonus question: Can JS functions be called from within JQuery? (this one, if negative might answer my first one, actually...)
In my understanding JQuery is nothing but a JS library. In many cases to introduce new functionality.
Yes, that is correct. In fact, your astute observation that people want to use jQuery where JS will suffice likely stems from a lack of understanding to this point!
Now why would someone use JQuery if an original JS function is available and not even too complex?
Someone may wish to use jQuery for certain functions if the JS-only equivalent is not well supported in all browsers.
Bonus question: Can JS functions be called from within JQuery? (this one, if negative might answer my first one, actually...)
Certainly! As you stated, jQuery is just a JavaScript library, and can be mixed with bits of plain JS without a problem.
