Why Are My Imported ES6 Module Functions Undefined in onclick Events?

ES6 Modules: Undefined Onclick Functions Post Importation

In ES6, modules establish a distinct scope to prevent namespace conflicts. When attempting to bind functions imported from a module using onclick, you may encounter a "ReferenceError: hello is not defined" error. This article provides solutions to this issue.

Solution 1: Using addEventListener

To handle onclick events for functions imported in modules, utilize addEventListener. Consider the following example:

<button type="button">

Solution 2: Exposing Functions to the Window Object (Not Recommended)

While not recommended due to potential global scope conflicts, you can also expose the imported function to the window object:

import {hello} from './test.js'
  
window.hello = hello

This allows you to access the function globally within your application.
