Pass a condition as an argument

I have this code:

$scope.checkIfReady = function(condition){ if(condition){ //do something }else{ //do something else } };

$scope.checkIfReady(word === "banana");

Say word is a global variable or something.

I can't seem to get this to work, is there anyway to do this? Or is there a work around?

Thanks!

I was trying ta pass a condition into the function! I wanted to pass word ==="banana", only evaluate it once I got to the IF-statement inside the function!

First one thing to clarify. You can't pass a conditional, but the result of a conditional. In other words word === "banana" will be evaluated first and the true/false will be passed to the function.

Assuming this is Angular 1.x, the issue is probably that word is outside of $scope. This also places it outside Angular's watch/update mechanisms.

Allright! Thanks!

It was really never an issue, i'm just trying to keep my code as DRY as possible, and then I thought of this and wondered if there was any way to do it!

Thanks again!
