Maximum conditions inside if in javascript
(3 answers)
Closed 2 years ago.
Is there a limit to how many conditions (e.g., logical OR conditions) that JavaScript allows me to have in an if statement, or can I have as many as I want?
If technically have not limits, but If you want a clean code, I recommend you use switch case.
Know more about how to write better conditionals statements here: https://www.digitalocean.com/community/posts/5-tips-to-write-better-conditionals-in-javascript
You can have as many as you want 🙂
There is no limit to use as many as conditions you want , but if we have so many conditions its always good practice to use SWITCH case to make code clean and efficent.

What does this regex mean

After searching for 'working onload event' I found Abhishek's anwser which used /in/ and after that, I tried searching for it but couldn't find anything useful about it, does someone know what does it do?
Without more context, /in/ looks like a regular expression (as mentioned by VLAZ), which you can learn more about here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions
I also like https://regex101.com/ for help reading or writing complex regular expressions. Just make sure to select the Javascript "flavor" as different languages implement regular expressions differently.

What are alternatives to document.write?
(11 answers)
Closed 3 years ago.
So guys, I made a little script to put in Tampermonkey for my presentations, but I have a problem.
What I want is to swap document.write(), but I don't know which function I could swap to replace it so that it leaves the code cleaner and more organized.
Besides document.write() is also not considered a good programming practice.
You could try to come up with your own function. But before taking any action, you need to think that there must be a injection into document body. You can try to use
document.body.appendChild()
and inside off that method, you can have some kind of html code.
Other than that you must generate a html document by using document.createDocumentFragment() or document.createElements().

400x Sorting Speedup by Switching a.localeCompare(b) to (a<b?-1:(a>b?1:0))
(5 answers)
Closed 3 years ago.
Im sorting an array of objects alphabetically but not sure which way is more efficient. Im currently using the .sort() method and its working fine but would using the localeCompare() be a better alternative?
The localeCompare function is absurdly slow on many browser. Avoid it if possible. The other locale functions are really bad too, particularly the number to string ones.

How can I reduce jQuery?
(7 answers)
Closed 1 year ago.
Is there a way to reduce jQuery to functions that I need.
In this case, I only want to use getJSON with the callback function. I don't need anything else of jQuery. Is there any way to cut this out?
Thanks,
Mike
You can do AJAX without jQuery. One explanation:
http://davekb.com/browse_programming_tips:easy_ajax:txt
Not really, there are a lot of dependencies, but modularity is planned.
As an aside, a getJSON() function isn't particularly hard to implement.

Why split the <script> tag when writing it with document.write()?
I don't really do Javascript programming and was hard to google this but have seen something like this in a couple of different places (by good developers):
document.writeln('<scr'+'ipt src="'+pcheck+'" type="text/javascript"></scr'+'ipt>');
With the split always between the r and the i. What does this achieve?
This is to prevent any script blockers from loading this script, because they cannot find the "script" word within the text.
