extendscript after effects if else statement how do i fix this up - extendscript

Question

this is my code the else statement is not firing well.
just test it if you can type in any effect and name it. I am trying to get the else statement to work check=false so that I can add my other action code to it.
var effectNameCollection = app.effects;
var check = false;
for (var i = 0; i < effectNameCollection.length; i++) {
var name = effectNameCollection[i].displayName;
if (name == "Color Matcher") {
check = true;
alert ("INSTALLED");
}else{
alert ("not installed");
}
}

I'm not entirely sure what your question is. But I will happily lend some advice. First of all, you likely don't want to have your alert code to be inside of the the for-loop. The way you have it now, it will fire an alert on every loop. I have 428 effects installed on my After-Effects, so that is a lot of alerts!
var effectNameCollection = app.effects;
var check = false;
for (var i = 0; i < effectNameCollection.length; i++) {
var name = effectNameCollection[i].displayName;
$.writeln(name);
if (name == "Color Matcher") {
check = true;
}
}
var chckAlert = check ? "INSTALLED" : "not installed";
alert(chckAlert);
The code above will log all of your installed effects to the terminal using $.writeln (extendscript's version of a console.log) and then will alert you if an effect with the name of 'Color Matcher' is installed.
The line:
var chckAlert = check ? "INSTALLED" : "not installed";
is just a condensed version of an if-else statement and is equivalent to:
var chckAlert = '';
if (check) {
chckAlert = "INSTALLED";
} else {
chckAlert = "not installed";`
}
