Projects for me work on for my learning?

So I'm learning full stack JavaScript, I know basic CSS, HTML and vanilla JavaScript with jQuery basics. I am just starting to learn Ajax, then react then on to backend, I wanted to build a project with what I know now. So vanilla JS, CSS and HTML. I have done JS basics, loops arrays and objects, HTML and CSS intro, the OOJS, callback function and array iteration courses. JQuery basics course, DOM scripting by example, ES2015 basics, regular expressions, HTML forms, I believe that is most of the courses I've taken here.

All projects welcome, I just want to challenge myself and make sure I understand how to use these things properly, like a project making me use array iteration and OOJS, making sure I can use it right, using event listeners and loops etc..

I cannot afford the techdegree right now or I'd be all over that! It is a future plan for me. Those projects sound amazing for me to learn with.

Thank you very much!
