X=(x=== images.length-1) ? 0 : x+ 1;
Please help me I have no idea, and it's for a school task that I have to hand in.
I'm not sure why people are so opposed to just answering the question. It's a ternary operation. It's a shortcut for an if/else clause. For this particular operation,
Is x equivalent (===) to images.length-1? If so, set X to 0. Otherwise, set X to x + 1.
This pattern is likely used to endlessly iterate over an array (images). Once it reaches the end, it resets to the first element in the array.

Can someone help me figure out why naming a variable changes the random value so much? I'm stumped.
In the first picture, you can see that the maximum value of the X value will be a random value between 25 and 300. However, EVER TIME I run the code, the lines are super short.
When I make a top_limit variable, shown in the second picture, the lines have true random lengths.
Can someone shed some light on what's happening here? There's no difference between the two pieces of code, in my opinion. One just has a variable name and the other doesn't. No?
When your random is in a for(,,), it is called on every iteration of the loop. So, in each iteration it changes.

I wanna get number of total array in NodeJS. Any way can do this?
For example: In picture have array from 0 > 558. Then I want a function to give the count is 559
Thank you.
Hieu
The array is only broken in console since it is very long: (i.e: if the length of array is longer than 100 then the console will break it to show it clearly..). if u logged the length then it will show 559, just do arr.length

I have an array of objects in Javascript (I use Vue.js2 in my project) and with .splice I can easily delete all the elements inside of it. The problem is, when only one element remains, I can't delete it because it stays there no matter what.
The easiest way to clean up an array is to make it [array].length = 0
You can use .length, .filter, .pop and im pretty sure you can .splice the last element, maybe there is something else u havent noticed yet.

I tried this : [fl]ady?[ing] ?[rb]ug!?
I know [fl]ad[y]?(ing)? ?[br]ug!? is an answer
Can this be solved using character sets only? Must match both.

fading rug!
I believe this should work for you
[fl]ad(y|ing)\s?[br]ug?
Check out http://www.regexpal.com/
Using character sets only? So, it doesn't matter what other letter combinations it matches as well? Mmm. Then
[fl]ad[giny]+[\sbrug!]+
would do. See: https://regex101.com/r/FJWJyM/1

So I wish to loop the javascript going to a certain page (without actually reloading/clearing console), then execute
href="javascript:doSomething(9)"
and then loop that by doing a function
Please help, thanks!
Assuming you want it to repeat - you can use an interval.
setInterval(function(){
doSomething(9);
},100); // the 100 is for 100 miliseconds
If you want it to repeat without having to wait (that is, block the code) you can use a normal while loop:
while(true){ // will loop forever since the condition is always "true"
doSomething(9);
}
