For example , declared activeTabIndex

How to see if i am setting the activeTabIndex event?

Here is the code:

 <TouchableOpacity onPress={() => setActiveTabIndex(0)} style={{ width: Dimensions.get("window").width / 4, padding: 5, alignItems: "center" }}>
          <Home height={30} width={22} fill={activeTabIndex == 0 ? "blue" : "#d4e6f1"} />
        </TouchableOpacity>

Where to write console.log(activeTabIndex) or something)

    `{activeTabIndex}` between the opening and closing JSX tags... – DecPK Jun 28 '21 at 07:19

    you don't have to use `console.log` just use `{activeTabIndex}` in the HTML and the value will get printed in the HTML. – DecPK Jun 28 '21 at 07:21
  • In `setActiveTabIndex` function have `console.log(whateverVarIsPassed)` – mplungjan Jun 28 '21 at 07:21
  • I just couldnt understand.. I mean i want to write to the console itself. `setActiveTabIndex()` this only sets the State, it wouldnt make sense if i wrote `setTabIndex(console.log(activeTabIndex)` because i set in there, if i wrote this, it wouldnt be set –  Jun 28 '21 at 07:36

    That does not make any sense. - you could do console.log(setTabIndex (activeTabIndex)) and return the tabIndex if you wanted, but not the other way around – mplungjan Jun 28 '21 at 07:47

  1. You can bind activeTabIndex to your JSX template eg. {activeTabIndex}
  2. You could add a console.log(index) in your setActiveTabIndex() method to see if it is getting fired.
