New chapter draft: Local variables and assignment

Hey everyone!

For those of you who've already purchased the book, we hope you're enjoying it so far. For those who haven't, here's an another reason to consider purchasing:

We've just made a draft of the next chapter available — Local Variables and Assignment:

In this chapter, we add a few new features to Wafer:

• let statements
• assignment expressions
• expression statements

Here's an example of what you can do now:

let pizzas = 1;
pizzas := pizzas + 1;
pizzas

If you've already purchased the book, you can access the latest version with the same activation link you got when you bought it. (If it's been a while — search your email for "Download WebAssembly from the Ground Up".)

Please take a look and let us know what you think!

✌️,

Patrick & Mariano
