# A Good Review is Just What The Doctor Ordered

I found two really great reference tools that will take your JavaScript game to another level.

I am about six months into my coding journey and I felt like I needed a better understanding of the core concepts of JavaScript.

I came to this conclusion when I entered the basic algorithm scripting portion of the freeCodeCamp.Org curriculum. It was beyond my normal level of challenge, and I found myself grasping for definitions and forgetting the basic functionality of previously learned functions and operators.

I contemplated starting all over, seeking other classes to build on my classes, finding help or just pushing forward feeling unsure.

My decision was to do a solid, complete review of what I've leaned thus far. This is how I spent my afternoon, and I already feel more confident about regaining my edge with JavaScript.

So if you are feeling overwhelmed, unsure or would like to hone your skills, checkout these two resorces.

[mdn webdocs\_\_-JavaScript data types and data structures](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures). These lessons break everything down into the tiniest details. I am looking forward to really diving in and sucking the marrow out of the knowledge they offer.

The other important reference tool, I'd like to recommend is [What are Browser Development Tool?](https://developer.mozilla.org/en-US/docs/Learn/Common_questions/Tools_and_setup/What_are_browser_developer_tools) This is another one by mdn, I love their library of solid, reliable answers.

With these words, I bid you...

Good night
