ElmJr is a new custom editor that allows you to create pictures and animations by programming in Elm.

Programming and designing has never been easier! You can avoid syntax (programming) errors by adding code using our Options tab, which shows you all the possible functions and properties you can use.

Through ElmJr, you can save your work to edit later and create as many animations/pictures as you like.

For those with viewing preferences, pinch the text in the text editor to increase or decrease the font size.

Download ElmJr to take the next step towards learning how to program in Elm!
