Destructuring primitive values in JavaScript

The doc page for destructuring assignment says

> This means if you try to destruct a primitive value, the value will
> get wrapped into the corresponding wrapper object and the property is
> accessed on the wrapper object.

Does this mean the following code?:

const { a, toFixed } = 1;

Is equivalent to:

const { a, toFixed } = {1};

No, it means that your 1 is turned into a Number instance, and then the destructuring acts on that.

So it's like

const { a, toFixed } = new Number(1);

The primitive value types number, string, and boolean all have corresponding wrapper types.

Every primitive type in javascript has its corresponding object.

In your example, the primitive type is number, so the corresponding object is Number

So, it will be equivalent to

const { a, toFixed } = new Number(1);
