How does AngularJS $watch these cases in an ng-repeat? -

I think AngularJS sets some watches on ng-repeat. What type of clock is set at this point?

In addition to this, can anyone tell what happens in each of these scenarios? I want to know in this incident that I have many things, so the user is not being thrown out of the clocks which could have ended, I wrote it in another way.

 two  
  & lt; Div ng-repeat = "item in item" & gt; & Lt; Div & gt; {{Item.property | MyFormatter}} & lt; / Div & gt; & Lt; / Div & gt;   
 three  
  & lt; Div ng-repeat = "item in item" & gt; & Lt; Div & gt; {{Format (item.property)}} & lt; / Div & gt; & Lt; / Div & gt;   
 Four  
  & lt; Div ng-repeat = "item in item" & gt; & Lt; Div & gt; {{Item.something ()}} & lt; / Div & gt; & Lt; / Div & gt;  
  
 
 
 every  ng-repeat  will set a $ watch < At Code> Items  (if you look at it, most of this is the $ 100 Execution Function for the Watch Method). Each time an angular conducts,  items  will be checked by this clock function in  items . (Note that in the Digest cycle, this clock function can be called more than once).  
 Each  {{}}  sets a $ watch if something like {code> item.property  is inside of {{}} s, then it In the digestive cycle, dirty check is done at least once.  
 If a function is {{}} inside, then that function is said at least once in the Digest cycle.  
 I'm not sure about the  x I filter , but it seems that the filter is called at least once in each digest cycle, even if  x  does not change.
