lodash debounce not working in anonymous function

Question

Hello I cannot seem to figure out why the debounce function works as expected when passed directly to a keyup event; but it does not work if I wrap it inside an anonymous fu

Answer 1

Think easier

_.debounce returns a debounced function! So instead of thinking in terms of

$el.on('keyup'), function(){
   _.debounce(doYourThing,500); //uh I want to debounce this
}

you rather call the debounced function instead

var doYourThingDebounced = _.debounce(doYourThing, 500); //YES, this will always be debounced

$el.on('keyup', doYourThingDebounced);
