And not less ideas that could improve usability of existing ones, like conditionals, loops and self-reference in object literals, { if (cond) set {a: 1}, for (x of values) set {[x.name]: x}, b: thisob.x, c: {d: thisob.c}, } enhanced data transfer, dest.{a, b, [key]} = src default values, var x = arg ?? 1 optionality and mandatoryness, var x = f?(…)?.info![key] ?? "<not found>" scope objects and flow control in these, function foo(a=1, b=2) { scope bar { let c = 3 scope { let c = 4 log(a, b, bar.c, c) baz(scope.this) // a, b, c, bar baz(scope.arguments) // a, b break bar function environments, global.{*} = {a:1, b:2} var t = proxify({a:3, b:4}, global) withenv (t) foo() // 3 4 function foo() { console.log(a, b) } and so on. It seems everyone jumps on to “new same language” train when there is so much to do in what’s already not done.
