Review

In this unit, you learned more JavaScript syntax.

Congratulations! The goal of this unit was to continue introducing you to JavaScript. You learned about more data types like arrays and objects and you also learned how to debug JavaScript programs.

Having completed this unit, you are now able to:

• Read and write JavaScript syntax for arrays, loops, objects, and iterators

• Debug JavaScript code and parse error messages

• Solve code challenges related to the newly learned syntax

If you are interested in learning more about these topics, here are some additional resources:

• Codecademy Project - Create your own library of methods, Lodash

• MDN Guide to Objects

• Digital Ocean Tutorial for Iteration Methods

Learning is social. Whatever you’re working on, be sure to connect with the Codecademy community in the forums. Remember to check in with the community regularly, including for things like asking for code reviews on your project work and providing code reviews to others in the projects category, which can help to reinforce what you’ve learned.
