ES6 Object Destructuring Default Parameters
ecmascript-6, javascript
Solution
Yes. You can use "defaults" in destructuring as well:
(function test({a = "foo", b = "bar"} = {}) {
console.log(a + " " + b);
})();
This is not restricted to function parameters, but works in every destructuring expression.
Problem
I'm trying to figure out if there's a way to use object destructuring of default parameters without worrying about the object being partially defined. Consider the following: ``` (function test({a, b} = {a: "foo", b: "bar"}) { console.log(a + " " + b); })(); ``` When I call this with `{a: "qux"}`, for instance, I see `qux undefined` in the console when what I really want is `qux bar`. Is there a way to achieve this without manually checking all the object's properties?
