Const is a pretty good example, the closest I can think to emulating it in es5 is something like:
Object.defineProperty(this, 'five', {
enumerable: true,
writable: false,
value: 5,
configurable: false
});
If in global scope, 'five' will look like a const.
WeakMap and WeakSet have polyfills with minor caveats.
I guess you're defining language features as not "syntactic sugar" if they can't be absolutely 100% polyfilled.
