How does one run a function from application.js inside a .js.erb file?

I'd rather not have to duplicate said function.

DOESN'T WORK

app/assets/javascripts/application.js

$(document).on('pagecontainershow', function() {
  function someOtherFunction() {
    console.log('Hello world')
  }
  
  // ...
});

app/views/articles/create.js.erb

<% unless @article.errors.any? %>
  someOtherFunction();
<% end %>

WORKS

app/assets/javascripts/application.js

function someOtherFunction() {
  console.log('Hello world')
}
  
$(document).on('pagecontainershow', function() {
  // ...
});
