Question

Is there a better javascript algorithm for constantly checking a condition?

Some websites have never-ending scrolling like twitter, where every time you scroll down, new content comes up.

I want to modify the html inside the content that keeps appearing every time you scroll.

To do that, I have a recursive function that constantly changes those content every second.

For those of you who don't understand what I'm saying, imagine pressing a button to turn something on. The machine checks if the button is pressed, then checks if the button is pressed, then checks if the button is pressed, then oh hey it's pressed, do something, then check if the button is pressed, check if the button is pressed...etc.

There's definitely a less naïve way to do this with javascript, but I'm not sure how. I don't think there's event listeners that checks if new content has been loaded after scrolling down.

Answer 1

Here's an example of code I use to make everyone's username on QC the same color:
```javascript
function setSameUsernameColor(){
for(let i=0;i< document.getElementsByClassName('user-link username').length;i++){
if(document.getElementsByClassName('user-link username').style.display != "none"){ document.getElementsByClassName('user-link username').setAttribute('style','color:darkorange!important;'); } } setTimeout(setSameUsernameColor,1000); } ``` As you can see, I'm recursively calling the function every second to check if a username's color is orange, and if it is, change it. This is running forever.
