Good book for edge and coding?

     Hello, i'm trying edge, everything works well..till the code start.

i can copy things from other users or sites, but to understand would be beter, so that i know what i'm doing.

Is all the code i see, just html? and is it 4 or/and 5

or maybe a mix of different languages?

Does anybody know a good clear book...I'm dutch, prefer also dutch, but don't think there is something good.

So clear english is also good.

There is a book as Edge animate for dummies...but maybe not the best, for my wish???
