short syntax to call array of functions using lodash

Question

I believe, there is a shorter way (one line) to write this using lodash:

  _.forEach(eventListeners, function(callback) {
    callback(event);
  })

... but can't find yet

Answer 1

Lodash provides a utility function called _.over that returns a function that you can then call to pass some arguments to all of the functions you provided to _.over

Official documentation for _.over

var funs = [
  function(e) { console.log(e) },
  function(e) { console.log(e*2) },
  function(e) { console.log(e*3) }
];

_.over(funs)(10);

This will call all of the functions in the funs array with 10 as their argument, so in this case you should see in your console:

10
20
30

In your case specifically:

_.over(eventListeners)(event);
