Learn JavaScript: Classes and Modules

Easily produce multiple objects with the same property using classes and export and import modules.
Continue your JavaScript learning journey with Learn JavaScript: Classes and Modules. Reuse logic in different parts of our application by easily producing multiple objects that have the same properties using classes and exporting and importing modules. You will also learn about inheritance—a concept used to efficiently produce classes with similar properties.



### Skills you’ll gain
