How do I grab the checked value on init?

[cmcguff-myob]

I have some code on changing the checkbox that toggles some UI on/off, that piece is working fine per this code

$('input[name="leave_type[validate_balance]"]').change(function() {
	$('#threshold_options').toggle($(this).prop('checked'));
});

If I try and grab the value on init, it is always false, no matter what's been saved, how do I get the state of the checkbox on first load? Everything else works perfectly.

$('input[name="leave_type[validate_balance]"]').init(function() {
    // Always false
    alert($('input[name="leave_type[validate_balance]"]').prop('checked'));
});

This plugin has not been supported for more than 6 years. What's the point of writing anything here?

Are there other alternative? We are using this plugin a lot
