Is it best to handle ALL operations on points in the main animation loop?

Let’s say I have a particle sim using a Points object with ~10,000 points.

animate() {
for(let i = 0; i <; i++) {		
  //code goes here			
  this.points.geometry.getAttribute('position').needsUpdate = true; 
  this.points.geometry.getAttribute('color').needsUpdate = true; 

So, that loop is always firing in order to visually update the particles.

But let’s say the colors only update periodically. Is it more efficient to write a function like

updateAllColors() {
for(let i = 0; i <; i++) {		
  //change each point color here..

or to set a boolean like “needsColorUpdate = true”, and then inside my animation loop, whenever that flag is true, handle the color change there?

Basically, what’s better: adding a redundant iteration loop that only happens once in a while, OR, adding a boolean check that is constantly firing in the animation loop (even if the color update only happens once)?

nothing that is redundant should suck up cpu. if you can schedule the thing away and only set it when you need to this is surely better.
