Happy coding

obviously somthing is wrong with the code but i ve tried everything qoutes
cammel case adding { nothing works

Is it kind of strange that you have “onclick” twice?

The onclick property should be assigned a function reference.

This isn’t super clear but it means that you need to assign the name of the function, and not call the function.

To call a function you write it with brackets() at the end.

i took out the brackets at the end and still nothing

btn.onclick = changeBackgroudColor;

never mind i fixed it
