BlockLike.js is an educational JavaScript library that attempts to extend the block-based Scratch learning experience to JavaScript text-based programming.

Through three complete projects, you'll gain a hands-on understanding of how to use JavaScript and its various libraries to build a fully-functional site or app from scratch.

If you want to learn to create relatively simple online games using Javascript, then the HTML5 Game From Scratch Step By Step Learning JavaScript course is a great place to start.
