Is there a functional way to set a boolean true and keep it true?

I have some code in jQuery where I loop over an array and compare html values. When the values match, I put a boolean to true, and make sure it stays true.

var inArray = false;
$.each($myArray, function (index, value) {
  inArray = inArray || value.html() === $draggable.html(); // Once it's true, it'll stay true
});

Is there a nice functional way of writing this without having to use the variable?

Use grep:-

$.grep($myArray, function(n) {
    return n.html() === $draggable.html(); 
}).length > 0;

Break out of the loop once a true value is hit:

$.each($myArray, function (index, value) {
    inArray = inArray || value.html() === $draggable.html(); // Once it's true, it'll stay true
    return !inArray; //returning true goes to next iteration, returning false breaks out.
});
