Angular Components Interactions in Tamil - Parent to Child (Part 1) | Tamil Techie VinoPravin

29:14 why for loop? we can use console.log(changes['counterValue']['currentValue']);

[@TamilTechieVinoPravin]

Yes we can use directly like that if we know the properties of 'simpleChanges'. Just for a better understanding am using this `for loop` to underline that simpleChanges returns type array and also for letting users to know the available properties of simpleChanges.

how {{countervalue}} calls countervalue() function bro?

[@TamilTechieVinoPravin]

We cannot do that! Countervalue'ndra variable dhan anga bind panirupan. Not function. Can you please point out where exactly you got this doubt?

[@mohankumarm9430]

@@TamilTechieVinoPravin @ 37:20 {{countervalue}} should be written as {{_countervalue}}

@@mohankumarm9430 Actually the concept of getter and setter is pure typescript. so `set` and `get` accessors are exceptional. Neenge oru function munadi adha get'nu declare paninga'na u can access the function as a variable. You can read about this getters and setters in typescript documentation. The reason why we use this `get` and `set` is purely for data validation purpose. Adhuvum neenga indha format'la kudutha dhan adhu work agum. indha type accessors illama idhu direct'a possible illa. Am really happy that you watched all the methods from starting to end.
