i new dart , wonder if can, example, extend divelement class create custom elements in 1 line of code. looking this; class redbox extends divelement { redbox(text) { this.text = text; this.style.background = "red"; } } redbox mybox = new redbox("hello world"); document.body.append(mybox); of course have more complex elements custom functions. in general, possible? when try run this, get: implicit call super constructor 'divelement()' you can extend html elements, there few requirements. 1 you're running need redbox.created constructor, , can redirect super class. created must generative constructor, though can add factory constructors. another requirement element registered document.registerelement . try adding this: class redbox extends htmlelement { redbox.created() : super.created() { style.background = "red"; } factory redbox(text) => new element.tag('my-redbox')..te...

, define ir 3-address code type representation (i realize 1 can mean ast representation well). it understanding that, when writing best-practice compiler imperative language , code optimization happens both on ast (probably best using visitor pattern), , on ir produced ast.  (a) correct? (b) type of optimization steps best handled on ast before producing ir? (reference article/a list online welcome long deals imperative language)  the compiler i'm working on decaf (which might know) has deep cfg (single) class inheritance; i'll add features not part of such type coercion. hand-coded (using no tools whatsoever). not homework; writing fun.  (a) yes. (b) constant folding 1 example; cse another; in fact expression evaluation. ir-phase optimizations more results flow analysis.
